library: tweak formatting for readstat header and code

Browse Source 
This patch mostly just eliminates darn tab characters.

Plus the library function declarations and definitions
have been standardized. Most visibly, the input params
now have all been indented on their own separate line.

The following names were changed to more closely match
meminfo.c or provide a certain symmetry. Unfortunately
that also impacted some other pgms which were updated.

. 'procps_stat_get' evolved into 'procps_stat_get_sys'
. 'procps_stat_info' is now known as 'procps_statinfo'

[and just a little trailing whitespace was eliminated]
