anchao 1c91aec6ae tools/ and fs/procfs: Simplify .version file generation 
1.merge CONFIG_GIT_REVISION_STR into CONFIG_VERSION_BUILD
2.merge gen_getrev.sh into version.sh
3.generate version number if needed

Here is a sample output:
nsh> uname -a
NuttX  8.2 59fd8e12d3-dirty Dec 12 2019 15:48:00 sim sim
nsh> cat /proc/version
NuttX version 8.2 59fd8e12d3-dirty Dec 12 2019 15:48:01

Critical Section Monitor (sched/ and fs/procfs: Remove SCHED_IRQMONITOR_GETTIME to simplify the clock source selection: (1) Use up_critmon_gettime if SCHED_IRQMONITOR, (2) Call clock_systimespec if SCHED_TICKLESS, (3) Don't collect timing info for all other cases and move up_critmon_* to arch.h avoid the duplicated declaration.

fs/procfs README
================

  This is a tiny procfs file system that allows read-only access to a few
  attributes of a task or thread.  This tiny procfs fs file system can be
  built into the system by enabling:

    CONFIG_FS_PROCFS=y

  It can then be mounted from the NSH command like like:

    nsh> mount -t procfs /proc

Example
=======

  NuttShell (NSH) NuttX-6.31
  nsh> mount -t procfs /proc

  nsh> ls /proc
  /proc:
   0/
   1/

  nsh> ls /proc/1
  /proc/1:
   status
   cmdline

  nsh> cat /proc/1/status
