hgweb: add removeByClassName javascript function It removes all elements with specified class name from the document.

hgweb: add docFromHTML javascript function It takes a string with HTML markup and creates DOM document from it. The implementation is a part of code from https://developer.mozilla.org/en-US/docs/Web/API/DOMParser#DOMParser_HTML_extension_for_other_browsers

hgweb: add makeRequest javascript function This function performs an asynchronous HTTP request and calls provided callbacks: - onstart: request is sent - onsuccess: response is received - onerror: some error occured - oncomplete: response is fully processed and all other callbacks finished

hgweb: add format javascript function It replaces placeholders like '%key%' with replacement values given.

hgweb: add nextentry variable for easy pagination in changelog nextentry always contains the first entry not shown on current page (if there is such entry)

hgweb: always compute all entries and latestentry in changelog Get the whole list of entries before rendering instead of using lazy evaluation. This doesn't affect the performance for usual case when the entries are shown anyway. When both entries and latestentry are used, this performs unnoticeably faster, and for pages which use only latestentry (quite uncommon case) it would be a bit slower. This change will make it possible to get the first entry of the next page easily without computing the list twice.

templatefilters: add short format for age formatting Implements a short output format for ages e.g. "1 second ago" is abbrevated as "1s ago".

hgweb: remove unused argument of changelist function in changelog This doesn't change the behavior as the argument isn't used anyway, and it's a preparation to the next patches,

context: move evolution functions from changectx to basectx This is just a code move and corrects an overlook from my previous patch series that assumed only a changectx would want this functionality.

context: use correct spelling of committable

check-code: check C patterns against .h files

check-code: make casting style check more precise

log: make file log slow path usable on large repos Running "hg log <pattern or directory>" on large repos took a very, very long time because it first read ctx.files() for every commit before even starting to process the results. This change makes the ctx.files() check lazy, which makes the command start producing results immediately.

plan9: update util.py for cpython 2.7 build

parse_manifest: rewrite to use memchr memchr is usually smarter than a simple for loop. With gcc 4.4.6 and glibc 2.12 on x86-64, for a 20 MB, 200,000 file manifest, parse_manifest goes from 0.116 seconds to 0.095 seconds.

parsers: correctly handle a failed allocation
