bundle2: move the 'close' method off the unpackermixin This method is unrelated to unpacking and only used by the unbundle20 class. We move it there for clarity.

bundle2: clarify the docstring of unpackermixin methods The unpackermixin is a utility used to implement the bundle2 protocol. It should not be used when writing part handlers. We update the docstring to clarify this.

bundle2: add documention to 'part.addparams' There are some non-obvious limitations on the parameters of this method. Add some documentation where people will likely look to understand how to use this API.

test-patchbomb: disable sendmail tests on Windows These tests were failing, and there isn't a trivial way to execute a script on Windows [1]. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096497.html

show: fix corrupt json output with no bookmarks

show: tweak plain abort language for clarity

tests: print Unix style paths in *.py tests These tests don't support (glob). I didn't audit all tests, but these ones were failing.

revlog: make "size" diverge from "rawsize" Previously, revlog.size equals to revlog.rawsize. However, the flag processor framework could make a difference - "size" could mean the length of len(revision(raw=False)), while "rawsize" means len(revision(raw=True)). This patch makes it so. This corrects "hg status" output when flag processor is involved. The call stack looks like: basectx.status -> workingctx._buildstatus -> workingctx._dirstatestatus -> workingctx._checklookup -> filectx.cmp -> filelog.cmp -> filelog.size -> revlog.size

test-flagprocessor: add a case about hg status This shows how "hg status" is wrong - nothing changed but the file is labeled as "M".

test-http-proxy: add the Windows variant of "connection refused" The full error is "No connection could be made because the target machine actively refused it".
