c6eb13 increased stack usage such that perf-top now croaks on startup.
Take event_array and mmap_array off the stack to prevent segfault on boxen
with smallish ulimit -s setting.

recent userspace (F11) seems to already include the
linux/unistd.h bits which means we cannot include the version
in the kernel sources due to the header guards being the same.
Ensure we include the kernel version first.

The documentation about the perf-top build was outdated after
perfstat has been implemented. This updates it.

First very raw version at having a central 'perf' command and
a list of subcommands:
perf top
perf stat
perf record
perf report
...
This is done by picking up Git's collection of utility functions,
and hacking them to build fine in this new environment.
