Replace the old ecompress/ecompressdir implementation with the one used
in portage[mgorny]. This is a squashed version of a long series of
commits that gutted off parts of old logic, introduced the new code,
fixed ongoing bugs and finally restored the missing features. Given
the scale of changes, it is easier to review it as completely new code.
The duplicate model of ecompress/ecompressdir (both not exactly par
on features) has been replaced by a single helper that compresses
everything uniformly. Instead of complex path-wise processing,
a mark-file logic is used -- the same as in estrip. Additionally,
the functions are moved out of ebuild path to clearly indicate they are
internal API (they were not used in any ebuilds).
The new implementation is par on features with the old one. It supports
exclusion suffix lists, automatic decompression of already-compressed
files (with eqawarn-ing about its unreliability), lower bound for
compressed file size, hardlink breaking and symlink fixing. In other
words, there should be no regression upon replacing it.
