tests: support older version of bunzip2 and, possibly, gunzip too

tests: fix compatibility on Solaris

Better help for mq: Corrected synopses, get qcommit options from commands.py.

Add debugaddremove alias to addremove, so it doesn't show up in 'hg help'. Add an explicit description of 'hg commit --addremove'.

Always clean the build directory before installing for running the tests. Otherwise tests might run an old version, when e.g. commands.py.orig is moved back after a revert (old timestamp).

Corrected test output for deprecated addremove command.

deprecate addremove command.

make test-remove check some more cases.

add --after option to remove command.

fix file handling bugs on windows. add util.posixfile class that has posix semantics on windows. fix util.rename so it works with stupid windows delete semantics.

Make hg update more verbose by default (issue12) (including small changes to revert and backout to not show these stats with the exception of backout --merge) Show update stats (unless -q), e.g.: K files updated, L files merged, M files removed, N files unresolved Inform the user what to do after a merge: (branch merge, don't forget to commit) Inform the user what to do if a branch merge failed: There are unresolved merges, you can redo the full merge using: hg update -C X hg merge Y Inform the user what to do if a working directory merge failed: There are unresolved merges with locally modified files.
