test-subrepo-recursion: fix output on non-hardlink systems
There's a slight bug present where a topic doesn't get closed when it should.
This isn't a regression, so I've made a note in the test file.
test-subrepo-recursion: set progress.changedelay really high
This avoids subtopics from showing up, which were introduced by my recent
change that added progress bars to hardlink clones in some cases.
dirstate: use parsers.make_file_foldmap when available
This is a significant performance win on large repositories. perffilefoldmap:
On Linux/gcc, on a test repo with over 500,000 files:
before: wall 0.605021 comb 0.600000 user 0.560000 sys 0.040000 (best of 17)
after: wall 0.280530 comb 0.280000 user 0.250000 sys 0.030000 (best of 35)
On Mac OS X/clang, on a real-world repo with over 200,000 files:
before: wall 0.281103 comb 0.280000 user 0.260000 sys 0.020000 (best of 34)
after: wall 0.133622 comb 0.140000 user 0.120000 sys 0.020000 (best of 65)
This visibly impacts status times on case-insensitive file systems. On the Mac
OS X repo, status goes from 3.64 seconds to 3.50.
With the third-party hgwatchman extension [1], 'hg status' on the same repo
goes from 0.80 seconds to 0.65.

parsers: add a C function to create a file foldmap
This is a hot path on case-insensitive filesystems -- it's guaranteed to be
called every time 'hg status' is run.
This is significantly faster than the equivalent Python code: see the following
patch for numbers.
util.h: define an enum for normcase specs
These will be used in upcoming patches to efficiently create a dirstate
foldmap.
perf: make measuring foldmap perf work again
Rev
25c1d3ca5ff6 split the foldmap into two, but I forgot to update perf for
the changes.
parsers._asciitransform: also accept a fallback function
This function will be used in upcoming patches to provide a C implementation of
the function to generate the foldmap.
util: add normcase spec and fallback
These will be used in upcoming patches to efficiently create a dirstate
foldmap.
