History
Joseph Koshy 49874f6ea3 MFP4: Support for profiling dynamically loaded objects. 
Kernel changes:

  Inform hwpmc of executable objects brought into the system by
  kldload() and mmap(), and of their removal by kldunload() and
  munmap().  A helper function linker_hwpmc_list_objects() has been
  added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve
  the list of currently loaded kernel modules.

  The unused `MAPPINGCHANGE' event has been deprecated in favour
  of separate `MAP_IN' and `MAP_OUT' events; this change reduces
  space wastage in the log.

  Bump the hwpmc's ABI version to "2.0.00".  Teach hwpmc(4) to
  handle the map change callbacks.

  Change the default per-cpu sample buffer size to hold
  32 samples (up from 16).

  Increment __FreeBSD_version.

libpmc(3) changes:

  Update libpmc(3) to deal with the new events in the log file; bring
  the pmclog(3) manual page in sync with the code.

pmcstat(8) changes:

  Introduce new options to pmcstat(8): "-r" (root fs path), "-M"
  (mapfile name), "-q"/"-v" (verbosity control).  Option "-k" now
  takes a kernel directory as its argument but will also work with
  the older invocation syntax.

  Rework string handling in pmcstat(8) to use an opaque type for
  interned strings.  Clean up ELF parsing code and add support for
  tracking dynamic object mappings reported by a v2.0.00 hwpmc(4).

  Report statistics at the end of a log conversion run depending
  on the requested verbosity level.
