util: compression APIs to support revlog decompression
Previously, compression engines had APIs for performing revlog
compression but no mechanism to perform revlog decompression. This
patch changes that.
Revlog decompression is slightly more complicated than compression
because in the compression case there is (currently) only a single
engine that can be used at a time. However for decompression, a
revlog could contain chunks from multiple compression engines. This
means decompression needs to map to multiple engines and
decompressors. This functionality is outside the scope of this patch.
But it drives the decision for engines to declare a byte header
sequence that identifies revlog data as belonging to an engine and
an API for obtaining an engine from a revlog header.

cHg === A fast client for Mercurial command server running on Unix. Install: $ make $ make install Usage: $ chg help # show help of Mercurial $ alias hg=chg # replace hg command $ chg --kill-chg-daemon # terminate background server Environment variables: Although cHg tries to update environment variables, some of them cannot be changed after spawning the server. The following variables are specially handled: * configuration files are reloaded automatically by default. * CHGHG or HG specifies the path to the hg executable spawned as the background command server. The following variables are available for testing: * CHGDEBUG enables debug messages. * CHGSOCKNAME specifies the socket path of the background cmdserver. * CHGTIMEOUT specifies how many seconds chg will wait before giving up connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60
