Mark Geisert c4008b8bc0 Fix profiler error() definition and usage
Minor updates to profiler and gmondump, which share some code:
- fix operation of error() so it actually works as intended
- resize 4K-size auto buffer reservations to BUFSIZ (==1K)
- remove trailing '\n' from 2nd arg on error() calls everywhere
- provide consistent annotation of Windows error number displays

Fixes: 9887fb27f6126 ("Cygwin: New tool: profiler")
Fixes: 087a3d76d7335 ("Cygwin: New tool: gmondump")

Mark Geisert aa460cc0ca Cygwin: Have gmondump support ssp-generated gmon.out
Cygwin tool ssp generates gmon.out files with different address
resolution than other tools do. Two address bytes per bucket rather than
the usual four address bytes. Gprof can deal with the difference but
gmondump can't because the latter's gmon.out header validation fails.

- Remove the offending portion of the header validation code.
- Make sure all code can handle differing address resolutions.
- Display address resolution in verbose data dumps.
- Change "rawarc" to "struct rawarc" in certain sizeof expressions to
  avoid buffer overrun faults.
- When "-v" (verbose) is specified, note when there is missing bucket
  data or rawarc data.

Mark Geisert 99a4b087d4 Cygwin: Make gmondump conform to its doc + adjust doc
The doc for gmondump says 1 or more FILENAME are expected, but 0 is
handled. That's an oversight. Make invocation with 0 FILENAMEs print a
one-line help message.

Reword the beginning of profiler's description doc to clarify target's
child processes are run but only optionally profiled.

Cygwin: New tool: gmondump
This new tool was formerly part of 'profiler' but was spun out thanks to
Jon T's reasonable review comment.  Gmondump is more of a debugging tool
than something users might have need for.  Users would more likely use
gprof to make use of symbolic info like function names and source line
numbers.
