profiling: use vendored statprof and upstream enhancements (BC) Now that the statprof module is vendored and suitable for use, we switch our statprof profiler to use it. This required some minor changes because of drift between the official statprof profiler and the vendored copy. We also incorporate Facebook's improvements from the "statprofext" extension at https://bitbucket.org/facebook/hg-experimental, notably support for different display formats. Because statprof output is different, this is marked as BC. Although most users likely won't notice since most users don't profile.

crecord: use scmutil.termsize()

scmutil: extend termwidth() to return terminal height, renamed to termsize() It appears crecord.py has its own termsize() function. I want to get rid of it. The fallback height is chosen from the default of cmd.exe on Windows, and VT100 on Unix.
