fsmonitor: use custom stdint.h file when compiling with Visual C

Visual C/C++ 9, which Python 2.7 is compatible with, doesn't have C99
support and thus doesn't contain a stdint.h file.

This changeset adds a custom version of stdint.h, created specifically
for Visual C, and uses it when building with that compiler.

'''helper extension to measure memory usage

Reads current and peak memory usage from ``/proc/self/status`` and
prints it to ``stderr`` on exit.
