test-pager: add a test for pager with color enabled

http: support sending hgargs via POST body instead of in GET or headers narrowhg (for its narrow spec) and remotefilelog (for its large batch requests) would like to be able to make requests with argument sets so absurdly large that they blow out total request size limit on some http servers. As a workaround, support stuffing args at the start of the POST body. We will probably want to leave this behavior off by default in servers forever, because it makes the old "POSTs are only for writes" assumption wrong, which might break some of the simpler authentication configurations.

fsmonitor: flag msc_stdint as no-check-code I'd rather not modify code that we're vendoring, so I'm just marking it this way.

fsmonitor: use custom stdint.h file when compiling with Visual C Visual C/C++ 9, which Python 2.7 is compatible with, doesn't have C99 support and thus doesn't contain a stdint.h file. This changeset adds a custom version of stdint.h, created specifically for Visual C, and uses it when building with that compiler.

tests: handle getaddrinfo reporting "No address associated with hostname" This has been seen on some Fedora 23 systems.

httpconnection: remove obsolete comment about open() When httpsendfile was moved from url.py into httpconnection.py in e7525a555a64 (url: use new http support if requested by the user, 2011-05-06), the comment about not being able to just call open() became obsolete.

sslutil: allow multiple fingerprints per host Certificate pinning via [hostfingerprints] is a useful security feature. Currently, we only support one fingerprint per hostname. This is simple but it fails in the real world: * Switching certificates breaks clients until they change the pinned certificate fingerprint. This incurs client downtime and can require massive amounts of coordination to perform certificate changes. * Some servers operate with multiple certificates on the same hostname. This patch adds support for defining multiple certificate fingerprints per host. This overcomes the deficiencies listed above. I anticipate the primary use case of this feature will be to define both the old and new certificate so a certificate transition can occur with minimal interruption, so this scenario has been called out in the help documentation.

help: add empty lines to hostfingerprints section I think this is now much easier to read.

help: document requirements We didn't have unified documentation of the various repository requirements. This patch changes that.
