revlog: calculate base revisions iteratively
This is in preparation for generaldelta, where the revlog entry base field is
reinterpreted as the deltaparent. For that reason we also rename the base
function to chainbase.
Without generaldelta, performance is unaffected, but generaldelta will suffer
from this in _addrevision, since delta chains will be walked repeatedly.
A cache has been added to eliminate this problem completely.
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

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.
