osutil: use fdopendir instead of dirfd

They were simply not detected.

convert: svn -- fix 'exists'
Previously 'exists' erroneously returned False for empty dirictories. This is
wrong since we want to detect even empty 'branches/' or 'tags/'.

mpatch: Define Py_ssize_t for old pythons and use it instead of ssize_t.
See also PEP 353.
NOTE: Microsoft compilers (8 or earlier) does not have ssize_t.

mpatch: use int rather than ssize_t
We might need to be more clever than this to make Py2.5 happy.

osutil: improve portability
- manually inline mode_to_kind
- remove unused alloca include
- remove fstatat and associated bits
It's not obvious that there's an advantage to using fstatat in terms
of performance. The race-avoidance properties of fstatat aren't
terribly useful to us either. So best to avoid it until we figure out
how to use it portably.

bdiff: tweaks for large files
- adjust the common line threshold to .1%
this speeds up a delta of 7M lines of source from 10m to 40s
- adjust the scaling of the hash array down a bit as it was raising the peak
memory usage significantly

revlog: break up compression of large deltas
Python's zlib apparently makes an internal copy of strings passed to
compress(). To avoid this, compress strings 1M at a time, then join
them at the end if the result would be smaller than the original.
For initial commits of large but compressible files, this cuts peak
memory usage nearly in half.

chunkiter: handle large reads more efficiently
- for large reads, don't attempt to read more than necessary
- if we've gathered the exact number of bytes needed, avoid a string copy

revlog: avoid large yields in group()
Split large yields so that the downstream consumer (chunkbuffer) will avoid
some pain when reading ahead.
