util, posix: eliminate encodinglower and encodingupper 2ebe3d0ce91d claims this was needed "to avoid cyclic dependency", but there is no cyclic dependency. windows.py already imports encoding, posix.py can import it too, so we can simply use encoding.upper in windows.py and in posix.py. (this is a partial backout of 2ebe3d0ce91d)

hgweb: side-by-side comparison functionality Adds new web command to the core, ``comparison``, which enables colorful side-by-side change display, which for some might be much easier to work with than the standard line diff output. The idea how to implement comes from the SonicHq extension. The web interface gets a new link to call the comparison functionality. It lets users configure the amount of context lines around change blocks, or to show full files - check help (also in this changeset) for details and defaults. The setting in hgrc can be overridden by adding ``context=<value>`` to the request query string. The comparison creates addressable lines, so as to enable sharing links to specific lines, just as standard diff does. Incorporates updates to all web related styles. Known limitations: * the column diff is done against the first parent, just as the standard diff * this change allows examining diffs for single files only (as I am not sure if examining the whole changeset in this way would be helpful) * syntax highlighting of the output changes is not performed (enabling the highlight extension has no influence on it)

scmutil: 25% speedup in casecollisionauditor On a large repository, switching casecollisionauditor to lowercasing all file names at once rather than one at a time improves hg-add time by 25%.

obsolete: os.SEEK_END first appeared in Python 2.5 fixes 48c232873a54 failing for Python 2.4

tests: convert a push test to use revsets

outgoing: accept revset argument for --rev There may be a more generic way that would add revset support to more commands by adding revset support to addbranchrevs(), but given the proximity of the next code freeze, a minimal change seems like the better choice.

dirstate: drop assert

dirstate: eliminate redundant check parameter on _addpath() state == 'a' implies check I fail to see what the point of this check parameter is. Near as I can see, the only _addpath call where it was set to True was in add(), but there, state is 'a'. This is a follow-up to c2016bae3b97.
