bundle2: allow compression options to be passed to compressor Compression engines allow options to be passed to them to control behavior. This patch exposes an argument to bundle2.writebundle() that passes options to the compression engine when writing compressed bundles. The argument is honored for both bundle1 and bundle2, the latter requiring a bit of plumbing to pass the value around.

chg: check snprintf result strictly This makes the program more robust when somebody changes hgclient's maxdatasize in the future.

rebase: provide detailed hint to abort message if working dir is not clean Detailed hint message is now provided when 'pull --rebase' operation detects unclean working dir, for example: abort: uncommitted changes (cannot pull with rebase: please commit or shelve your changes first) Added tests for uncommitted merge, and for subrepo support verifying that same hint is also passed to subrepo state check.

revset: parse variable-length arguments of followlines() by getargsdict()

parser: extend buildargsdict() to support variable-length positional args This can simplify the argument parsing of followlines(). Tests are added by the next patch.

parser: make buildargsdict() precompute position where keyword args start This prepares for adding *varargs support. See the next patch.

chg: change server's process title This patch uses the newly introduced "setprocname" interface to update the process title server-side, to make it easier to tell what a worker is actually doing. The new title is "chg[worker/$PID]", where PID is the process ID of the connected client. It can be directly observed using "ps -AF" under Linux, or "ps -A" under FreeBSD.

chgserver: add the setprocname interface This allows clients to change its process title freely.

hgweb: use archivespecs for links on repo index page too Moving archivespecs to the module level allows using it from other modules (such as hgwebdir_mod), and keeping a reference to it in requestcontext allows current code to just work.

hgweb: use util.sortdict for archivespecs Thus we allow dict-like indexing and "in" checks, and also preserve the order of archive types and can generate links in a certain order (so requestcontext.archives is no longer needed).
