[gentoo-dev] [PATCH] webapp.eclass: optimize webapp_serverowned() and inlining webapp_strip_*()

[Florian Schmaus]

Some ebuilds invoke webapp_serverowned with -r, causing the eclass to
iterate over a large set of files. Within the iteration body, the eclass
forks multiple times to invoke the webapp_strip.

This optimizes webapp_serverowned() by replacing the call to the "strip"
functions with an equivalent invocation of find that iterates over all
the files.

Furthermore, all remaining invocations of webapp_strip_*() are inlined.

Closes: https://bugs.gentoo.org/781860
