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.

rather than treating the array as a heap.
(pending_signals::del): Ditto.

@stage2_werror_flag@ down to configure in stages 2 and 3.
* Makefile.in: Regenerate.
* Makefile.tpl (new-bootstrap): Set CC and CC_FOR_BUILD in configure
for stages 2 and 3 as well as in make. As a consequence, remove
OUTPUT_OPTION (now detected by configure) from the flags passed down
to make.
* Makefile.in: Regenerate.
* Makefile.tpl (new-bootstrap): Fix typo.
* Makefile.in: Regenerate.
* 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.

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.
into their proper sections.
* Makefile.tpl (top level bootstrap support): Move disabling
of coverage flags from 'make' to 'configure'; improve comments.
* Makefile.in: Regenerate.
* Makefile.tpl (experimental top level bootstrap) Move stage1
language setting from all- target to configure- target; disable
intermodule optimization in stage 1; prevent gratuitous rebuilds
of stage 1.
* Makefile.in: Regenerate.
* configure.in: Comma-separate stage 1 language list for top
level bootstrap.
* configure: Regenerate.
* Makefile.tpl: Clean up experimental top level bootstrap support:
note known problems; set CONFIG_SHELL; don't set BUILD_CC; relocate
prev-gcc in configure- targets as well as all- targets.
* Makefile.in: Regenerate.
output.

children will have the right size heap.

(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.
