[PATCH v3 0/1] qga: add command 'guest-get-cpustats'

[zhenwei pi <pizhenwei@bytedance.com>]

v2 -> v3:
- Rename 'GuestOsType' to 'GuestCpuStatsType'.
- Add 'linux' into polluted_words, rename 'linuxos' to 'linux'. Remove
  'windows' from 'GuestCpuStatsType', because currently we don't use it.

v1 -> v2:
- Konstantin & Marc-André pointed out that the structure 'GuestCpuStats'
  is too *linux style*, so re-define it to 'GuestLinuxCpuStats', and use
  an union type of 'GuestCpuStats'.

- Modify comment info from 'man proc', also add linux version infomation.

- Test sscanf return value by '(i == EOF)' (To Marc-André: name is declared
  as 'char name[64];', so we can't test '!name').

- Suggested by Marc-André, use 'int clk_tck = sysconf(_SC_CLK_TCK);'
  instead of hard code.

v1:
- Implement guest agent command 'guest-get-cpustats'
