darcs2hg: pause and resume support, date extraction from commit hash, does not break on empty commits

darcs2hg: improved logging

darcs2hg.py: use darcs patch hash as patch identifier The use of the patch name is dangerous when duplicate names exist. In case of a duplicate name the second patch and all its dependancies are merged into a single mercurial patch. The patch identifier (hash) is always unique.

adding local_hostname option to smtp configuration

Respect "Connection: close" headers sent by HTTP clients. A HTTP client can indicate that it doesn't support (or doesn't want) persistent connections by sending this header. This not only makes the server more compliant with the RFC, but also reduces the run time of test-http-proxy when run with python 2.3 from ~125s to ~5s (it doesn't affect it with python 2.4, which was already ~5s).

allow use of extensions in python hooks extensions are loaded with hgext_ prefix, try to use them if the module is not found in the normal path

diff: add -b/-B options

use __contains__, index or split instead of str.find str.find return -1 when the substring is not found, -1 evaluate to True and is a valid index, which can lead to bugs. Using alternatives when possible makes the code clearer and less prone to bugs. (and __contains__ is faster in microbenchmarks)

coding style: use spaces instead of tabs

bdiff: improve worst case behavior by 100x. on 5.8MB (244.000 lines) text file with similar lines, hash before this change made diff against empty file take 75 seconds. this change improves performance to 0.6 seconds. result is that clone of smallish repo (137MB) with some files like this takes 1 minute instead of 10 minutes. common case of diff is 10% slower now, probably because of worse cache locality. but diff does not affect overall performance in common case (less than 1% of runtime is in diff when it is working ok), so this tradeoff looks good.

Changed default timeout for run-tests.py from 30 to 180 seconds. As e.g. test-http-proxy already takes quite some time (about a minute here) and tests usually should clean up after themselves, the timeout should only be hit in case of other problems.
