libq/xarray: Handle NULL arrays in xarraysort()
Some invocations of `q` may try to call `xarraysort(NULL, 0)`.
One example is `qlop -a foo` where `foo` was never unmerged.
Instead of requiring every call of `xarraysort()` to take care of `NULL`
arguments, `xarraysort()` now exits early if `arr->eles == NULL`.
Closes: https://github.com/gentoo/portage-utils/pull/28

libq/contents: fix invalid access problem pointed out by valgrind
len represents the entire string length, but we start scanning after the
line identifier, so substract that size from len, such that we don't
start scanning after the end of the input string.

Coverity correctly deduced here, that if we used cached stat, we didn't
use the cache, but a bogus memory struct instead. Ensure we always use
a populated stat value.

libq/atom: perform correct SUBSLOT matching in compare
fixup after ef14d5f7bb09b8a90e827262798ebd1fde58913a
now SUBSLOT is never NULL, ensure we check it was explicitly set or not,
which is what used to be NULL.

libq/atom: fix atom_clone wrt SUBSLOT
A thinko that assumed SUBSLOT was stored in SLOT (which it usually is)
caused it to never be copied, since obviously SLOT is terminated, so
SUBSLOT, even when originally part of SLOT, would never be contained
within SLOT.
Just copy it separately, which has the additional bonus of being less
obscure.

libq/tree: build cache for Packages/binpkgs
Because we cannot trust Packages file to be in sorted order, and the
order isn't what we want (most recent match on top), we have to sort the
pkgs found in Packages, so make that exploit the cache, which will speed
up any subsequent tree_match_atom calls, which is good.
Do the same for binpkg trees, since they also cannot be cached
otherwise.

libq/tree: add ability to match latest version per package in tree_match_atom
Allow retrieving the latest version per package matching the input atom.
E.g. a search for dash would return both app-shells/dash as well as
app-emacs/dash using LATEST, while FIRST would only return the app-emacs
one (or whichever came first while traversing).

libq/tree: make tree_match_atom return path for each match
Along with some changes to make sure returned atoms remain valid (e.g.
not getting an expired pointer for category name), build a patch to the
returned objects, that should allow opening the ebuild or something.

libq/atom: adapt atom_explode to take an optional category
Sometimes we don't have the category available in the to be parsed
string, but in a separate string. Make it relatively cheap to use this
category, compared to having to allocate and format a string to make
atom_explode pick it up.

libq/tree: fix metadata cache after realloc
A realloc caused a relocation of pointers, which also changed the value
of Q__md5_ and Q__eclasses_ which are secretly used to store len and
pos, so make sure we reset them to correct values after a relocation
takes place.
While at it, reduce the allocation requirements by only considering the
really needed space (over-allocate less here).

libq/tree: rework tree_match_atom to return a list of results
Major change is that multiple results are returned, somewhat controlled
by flags, and that the results are valid until the tree is closed. Each
match result needs to be closed individually though.
This required some hoops to make it work with Packages file or binpkg
repos. The latter are largely simulated now, and do not really benefit
from the cheaper point and lookup approach that tree_match_atom tries to
provide.

libq/tree: have tree_read_file_binpkg populate some meta fields
The SHA1 and SIZE fields might be necessary, so psuedo fill them in
here, as we don't have a meta that contains them, except the file
itself.

libq/tree: ensure meta fields are clear when not set

metadata).

libq/tree: help for Coverity 206550 String not null terminated
the zalloc on buffer + 1 size should ensure null-termination, but
Coverity doesn't quite see this, so explicitly null-terminate the
string, thereby slightly optimising zalloc away for plain malloc

libq/tree: add initial tree_match_atom with caching
tree_match_atom is meant for retrieving the best matching element from a
tree based on a query. It caches the underlying packages it traverses,
such that repetitive lookups will benefit from previous lookups. This
comes in handy for recursive scenarios such as when
calculating/resolving dependencies.

Don't check bounds if there is no data retrieved, and make sure we check
the bounds on the data length, not index length.

libq/xpak: try to seek to XPAKSTART in _xpak_open
To make it easier to deal with assembled files (like binpkgs) just embed
the offset logic in _xpak_open. This makes qxpak operate directly on
tbz2 files, removing the need to split out using qtbz2 first.

libq/tree: ensure we don't work on garbage on sorted pkg trees
The contents of dirents come from a static buffer that may get
re-purposed when the next readdir call is made, so we cannot rely on it
staying around. In particular on large directories, the entries will
get recycled, and hence garbage appear. Thus, we need to copy the
entries, and free those copies. The behaviour before
f855d0f4f7c3e6e570a1ad3dc98d737e78996e4a was actually using scandir
which allocates space for all dirents. We now basically just copy the
bit we need, instead of the full dirent.
Thanks Sergei Trofimovich (slyfox) for digging into this case and
providing a VDB which displayed the problem.

libq/tree: greatly simplify tree_get_vdb_atoms
use tree_foreach_pkg_fast() to construct the set of string atom names
using atom_format()
this function likely should be removed as the consumer should work on
the atoms instead of their string representation

libq/tree: avoid calling qsort with empty set
Encountering an empty directory in tree_next_pkg_int will not populate
cat_ctx->pkg_ctxs, so avoid calling qsort with it. While at it, avoid
calling it for a single entry too.

libq/atom: document atom_to_string takes any matching prefix string
Basically any matching prefix string will work, so CATEGORY could be
CATE or C or anything inbetween the full name and its first character.
Care should be taken, S for instance, selects SLOT, not SUBSLOT, and it
won't warn either.

libq/atom: split out SLOT and SUBSLOT for atom_format
it is a bit unclear whether SUBSLOT is part of SLOT or not, but PMS
doesn't allow '/' so probably it's supposed to be separate, hence split
them up, to format the former combo use %[SLOT]%[SUBSLOT]

libq/tree: make pkg sorting based on atom_compare
Using alphasort on pkgs makes little sense because they include version
information that needs careful extraction and matching rules as
implemented by atom_compare.
In order to use atom_compare efficiently, that is, reusing the
atom_explode work done for the elements while running qsort, use
tree_get_atom, which caches the retrieved atom. Extra bonus is that any
function that retrieves the atom afterwards gets it for free. This
speeds up significantly apps that need to construct atoms, such as
qkeywords.

libq/cache: add mode for plain ebuilds (not using any cache)

cache appears available. This way cache can be used to transparently
query a repository in the best possible way.

rm_rf_at: ensure return code makes sense
Don't blindly ignore errors, just run statements that should succeed and
register success.

rm_rf: make shallow wrapper around rm_rf_at
Since rm_rf_at now removes the object being pointed at, rm_rf doesn't
have to try doing that again.

rm_rf_at: remove the object path points to
To better emulate 'rm -Rf' behaviour, if path points to a file, just
remove it. If it points to a directory, remove that directory instead
of leaving the (now) empty directory behind.

xstrdup: avoid warning about clobbering t
When using optimisation, the compiler does something to a char pointer
it doesn't do to a void pointer, so use a couple of casts to avoid a
clobber warning.

colors: add support for color=color mappings
This patch is based on the work by Pavel Balaev <pascal <AT> unixdev.ru>.
Add support for color=color mappings. While at it, make color remapping
independent of the order in which they are defined in color.map.

atom_explode: support inversed ranges, e.g. !>P-x.y
For bug #608960 we need to be able to handle odd atoms like
!<logrotate-2.3.0 (as used by sys-apps/portage). This adds support for
this construct.

Just use an int to store getline return, then ensure it is positive,

rm_rf_at: fix recurse logic for non-Linux
EISDIR is non-POSIX used by the Linux kernel, but not returned on e.g.
Darwin, so use the EISDIR shortcut, if we can, else perform a stat to
figure out if we're dealing with a directory or not.

atom_explode: be more careful with eating suffix letters
Make sure we don't just eat a char at the end of the atom, because if
that char appears after a -, it will be seen as version part. An
example is xerces-c, where the parsed atom form would just be xerces.

compat: do not include sys/dir.h on linux systems
This is an old compat header that might not exist on POSIX systems.
Since Linux C libs don't generally need it, avoid it there.

xsystem: fix fchdir handling with <linux-3.5
We use O_PATH with the vdb dirs, and sometimes we try to fchdir with
those fds. Unfortunately, fchdir doesn't work with O_PATH and linux-3.5
leading to errors like:
>>> pkg_postrm
merge: fchdir failed: Bad file descriptor
When fchdir fails with EBADF, assume it's because of an older kernel,
and fall back to using the /proc/self/fd/ path indirectly.
