library: standardize all the 'context' structure names

Browse Source 
This patch attempts to standardize the naming of those
most important (declared not defined) context structs.

The present practice represents a hodge podge of names
only some of which reflect the source /proc file name.
And 2 of those file names embed a literal 'info' which
is likely the origin of that required parm identifier.

Now we'll append a universal '_info' to such structure
names, while including the names of those /proc pseudo
files where possible. In any case, that context struct
will *always* begin with the actual module/header file
name. And only the following two sound a little weird!

---------> 'meminfo_info' + 'slabinfo_info' <---------
