Subject: [PATCH v2 03/14] perf: Split up util.h

util.h is a hodgepodge which consists of:

1) some compatibility macros and system includes
2) declarations for util.c
3) declarations for other .c files

Move the compatibility macros and system includes to compat-util.h.
Move the declarations for other .c files to their respective proper
locations, creating new header files where needed.

This makes the code better organized and will make it easier to untangle
these pieces into separate components later.
