(fhandler_dev_tape::driveno): New method.
(fhandler_dev_tape::drive_init): New method.

using the O_TEXT flag as ... flag.

tape specific code.
(fhandler_dev_raw::raw_read): Ditto.
(fhandler_dev_raw::dup): Ditto.
* fhandler_tape.cc: Rewrite tape operations entirely. Implement
new tape driver classes mtinfo, mtinfo_drive and mtinfo_part.
Reduce fhandler_dev_tape methods to mostly just calling appropriate
mtinfo_drive methods.
(mtinfo_init): New function adding the mtinfo shared memory area.
* mtinfo.h: New file, containing the definition of the new tape
driver classes.
* shared.cc: Include mtinfo.h.
(offsets): Add entry for mtinfo shared memory area.

* include/cygwin/mtio.h: Change and add various comments. Add GMT_xxx
macros for new generic flags. Add MT_ST_xxx bitfield definitions

handling whenever a '\' is detected.
* signal.cc (sigaction): Make strace output more informative.
* sigproc.cc (pending_signals::add): Just index directly into signal array
rather than treating the array as a heap.
(pending_signals::del): Ditto.
(wait_sig): Don't send signal if we already have a similar signal queued.
* sigproc.h (call_signal_handler_now): Remove obsolete declaration.
* fhandler.h (class fhandler_dev_dsp): Add class Audio, class Audio_in
and class Audio_out members and audio_in_, audio_out_ pointers so
that future changes are restricted to file fhandler_dsp.cc.
* fhandler_dsp.cc (fhandler_dev_dsp::Audio): Add this class to treat
things common to audio recording and playback.
Add more format conversions.
(fhandler_dev_dsp::Audio::queue): New queues for buffer management
to fix incomplete cleanup of buffers passed to the wave device.
(fhandler_dev_dsp::Audio_in): New, added class to implement audio
recording.
(fhandler_dev_dsp::Audio_out): Rework to use functionality provided
by fhandler_dev_dsp::Audio. Allocate memory audio buffers late,
just before write.
(fhandler_dev_dsp::Audio_out::start): Size of wave buffer allocated
here depends on audio rate/bits/channels.
(fhandler_dev_dsp::Audio_in::start): Ditto.
(fhandler_dev_dsp::setupwav): Replaced by following function.
(fhandler_dev_dsp::Audio_out::parsewav): Does not setup wave device
any more. Discard wave header properly.
(fhandler_dev_dsp::open): Add O_RDONLY and_RDWR as legal modes.
Protect against re-open. Activate fork_fixup.
(fhandler_dev_dsp::ioctl): Protect against actions when audio is
active. SNDCTL_DSP_GETFMTS only returns formats supported by
mmsystem wave API, not all supported formats. SNDCTL_DSP_GETBLKSIZE
result now depends on current audio format.
(fhandler_dev_dsp::fixup_after_fork): Call fork_fixup for the Audio
classes to let them duplicate the CRITICAL_SECTION.
output.
(cygheap_fixup_in_child): Set alloc_sz to passed in size to ensure that
children will have the right size heap.
(_csbrk): Make output conditional on DEBUGGING.
(child_info::cygheap_alloc_sz): New field.
* cygheap.cc (init_cheap): Reduce size of cygwin stack until minimal hit when
attempting initial allocation.
(cygheap_setup_for_child): Use alloc_sz to create secondary memory mapped
entry. Store alloc_sz in cygheap_alloc_sz.
(cygheap_fixup_in_child): Use cygheap_alloc_sz to map parent's cygheap.
* cygheap.h (_CYGHEAPSIZE_SLOP): New define.
(CYGHEAPSIZE): Use _CYGHEAPSIZE_SLOP.
real swap file usage by requesting SystemPagefileInformation. Use
GlobalMemoryStatus as fallback.
