changegroup: wrap some ** expansions in strkwargs

obsolete: reuse _fm1metapair for computing _fm1metapairsize It's evaluated at import time, so it seems silly to not reuse the constant name.

setup: fix installing in a mingw environment The addition, in 9a4adc76c88a, of a hack for the MSVC compiler class was overwriting the original class for the Mingw32CCompiler class, leading to an error when the HackedMingw32CCompiler is instantiated.

osx: delay version computation on macOS builds Before this patch, HGVER would be evaluated at the beginning of the make execution, and would be unset because build/mercurial/ doesn't exist yet at that point. Now we compute the version after the `make install` run has completed. This is backported to stable from 8626b44516c1, but that revision had an error in the shell invocation syntax.

evolution: rename unstable to orphan Rename unstable to orphan in all external user-facing output. Only update user-facing output for the moment, variables names, templates keyword and potentially configuration would be done in later series. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D214

bundle2: load hookargs from bundleoperation into transaction when started one When a transaction is started, we must load the hookargs from the bundleoperation object to the transaction so that they can be used in the transaction. Also this patch makes sure no more hookargs are added to the bundleoperation object once the transaction starts. This is a part of porting fb extension bundle2hooks to core.

bundle2: add the capability to store hookargs on bundle operation object There are extensions like pushrebase, pushvars which run hooks on a server before taking the lock. Since the lock is not taken, transaction is not there, so the hookargs can't be stored on the transaction. Adding hooksargs to bundle operation object will help in running hooks before taking the lock. This is a part of moving fb's extension bundle2hooks to core.

branchmap: revert c34532365b38 for Python 2.7 compatibility Old versions of python 2.7 don't like that the second argument to struct.unpack_from is a bytearray, so the change removing the util.buffer around that argument in branchmap broke running on older versions of python 2.7.

ssh: unban the use of pipe character in user@host:port string This vulnerability was fixed by the previous patch and there were more ways to exploit than using '|shellcmd'. So it doesn't make sense to reject only pipe character. Test cases are updated to actually try to exploit the bug. As the SSH bridge of git/svn subrepos are not managed by our code, the tests for non-hg subrepos are just removed. This may be folded into the original patches.
