getbundle: send highest changegroup format supported by both side When using bundle2, we find the common subset of supported changegroup-packers and we pick the max of them. This allow to use generaldelta aware changegroup through bundle2.

changegroup: allow use of different cg#packer in getchangegroupraw This will allow the use of general delta aware changegroup formats.

changegroup: introduce "raw" versions of some commands The commands getchangegroup, getlocalchangegroup and getsubset now each have a version ending in -raw. The raw versions return the chunk generator from the changegroup packer directly, without wrapping it in a chunkbuffer and unpacker. This avoids extra chunkbuffers in the bundle2 code path. Also, the raw versions can be extended to support alternative packers in the future, to be used from bundle2.

win32: remove Mercurial.ini file from Inno Setup installer (issue4435)

win32: fix win32 installers generation cd0c51c07e5f introduced a typo preventing a proper generation of the installers. Also remove ConcatenateFiles() function as it is no more required.

patchbomb: add label and color to the confirm output The current output is mostly a wall of text. This makes it hard to actually check something for people with lazy eyes. We use labels and colors to make it more joyful (and get the patch summaries to stand out). The colors have been arbitrarily choosen. They can be changed later if someone has a more scientific choice.

tests: write hgrc of more than two lines by using shell heredoc Here document should be readable than repeating echo commands.

perf: use a formatter for output We use a `formatter` object in the perf extensions. This allow the use of formatted output like json. To avoid adding logic to create a formatter and pass it around to the timer function in every command, we add a `gettimer` function in charge of returning a `timer` function as simple as before but embedding an appropriate formatter. This new `gettimer` function also return the formatter as it needs to be explicitly closed at the end of the command. example output: $ hg --config ui.formatjson=True perfvolatilesets visible obsolete [ { "comb": 0.02, "count": 126, "sys": 0.0, "title": "obsolete", "user": 0.02, "wall": 0.0199398994446 }, { "comb": 0.02, "count": 117, "sys": 0.0, "title": "visible", "user": 0.02, "wall": 0.0250301361084 } ]

bundle2: support a "version" argument in `changegroup` part When included, this mandatory parameter (mandatory == cannot be ignored) lets the part handler select the right cgunpacker class.
