  - pmcstat(8) gprof output mode fixes:
  
    lib/libpmc/pmclog.{c,h}, sys/sys/pmclog.h:
    + Add a 'is_usermode' field to the PMCLOG_PCSAMPLE event
    + Add an 'entryaddr' field to the PMCLOG_PROCEXEC event,
      so that pmcstat(8) can determine where the runtime loader
      /libexec/ld-elf.so.1 is getting loaded.
  
    sys/kern/kern_exec.c:
    + Use a local struct to group the entry address of the image being
      exec()'ed and the process credential changed flag to the exec
      handling hook inside hwpmc(4).
  
    usr.sbin/pmcstat/*:
    + Support "-k kernelpath", "-D sampledir".
    + Implement the ELF bits of 'gmon.out' profile generation in a new
      file "pmcstat_log.c".  Move all log related functions to this
      file.
    + Move local definitions and prototypes to "pmcstat.h"
  
  - Other bug fixes:
    + lib/libpmc/pmclog.c: correctly handle EOF in pmclog_read().
    + sys/dev/hwpmc_mod.c: unconditionally log a PROCEXIT event to all
      attached PMCs when a process exits.
    + sys/sys/pmc.h: correct a function prototype.
    + Improve usage checks in pmcstat(8).
