#1 PCP - MacOSX - task_t type conflicts w/ mach_types.h

[mtw]

Problem Description
----
Build fails on MacOS 10.3.9 because the file src/pmlogger/logger.h
defines a type, i.e. task_t, that conflicts with the task_t type defined
in: /usr/include/mach/mach_types.h

The affected files (all in src/pmlogger) are:
logger.h
callback.c
check.c
dopdu.c
gram.save.c
gram.y
pmlogger.c

Suggested Solution
----
Change the name of the pcp-internal type to pcp_task_t, in all affected
source files.
