revlog: remove the last bits of punched/shallow Most of it was removed in e7483ec3c374, but a few pieces were accidentally left behind.

util: make readfile() operate in binary mode writefile() and appendfile() are already working that way.

cmdutil: normalize log message eols when reading from file This will be necessary once util.readfile() operates in binary mode. While changelog.add() already normalizes the message, doing so in logmessage() is required as ui.edit() or others expect messages with LF only.

match: make 'listfile:' split on LF and CRLF We want util.readfile() to operate in binary mode, so EOLs have to be handled correctly depending on the platform. It seems both easier and more convenient to treat LF and CRLF the same way on all platforms.

progress: remove useless statement left by bab267e7fc1a

debugbuilddag: simplify tags serialization a bit

httprepo: send 100-continue on POSTs if using http2

url: use new http support if requested by the user The new http library is wired in via an extra module (httpconnection.py), as it requires similar but different plumbing to connect the library to Mercurial's internals and urllib2. Eventualy we should be able to remove all of keepalive.py and its associated tangle in url.py and replace it all with the code in httpconnection.py. To use the new library, set 'ui.usehttp2' to true. The underlying http library uses the logging module liberally, so if things break you can use 'ui.http2debuglevel' to set the log level to INFO or DEBUG to get that logging information (for example, ui.http2debuglevel=info.)

Import new http library as mercurial.httpclient. This is revision a4229f13c374 of http://py-nonblocking-http.googlecode.com/ with a no-check-code comment added to the end of each file using `for fi in $(hg manifest | grep mercurial/httpclient/) ; echo '# no-check-code' >> $fi`.

commands, i18n: add translation hint for split message

mq: don't hide the patch module

patch: remove unused ui arg to iterhunks
