commented-out start_remote calls.
* remote-hms.c, remote-adapt.c, remote-mm.c, remote-udi.c: Remove

functions which live below the target vector into this file to
facilitate host/target/native split. Also, make them static.

(child_attach): Don't require exec file.
through the target vector.
* inferior.h (kill_inferior_fast): remove declaration.

operands to memory management instructions, from WRS.

(FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command.
Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.

(full_filename): Don't prepend dirname if filename begins with /.
(breakpoint_notify, kernel_dispatch): Deal with DynamicLoad
messages properly!!
(getpty (NCR)): Lotsa bug fixes...
(kernel_dispatch (case StopRType)): Use kill() instead of
killpg() so we can deal with losing systems...
(wait_for_events): Work around NCR select() lossage. It doesn't
zero out readfds when select() returns zero.
(energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
getcwd() instead of getwd() (NCR getwd() seg faults).
(energize_wait): Use sigaction() for NCR. Their version of signal()
is unreliable by default.
places where we must notify kernel of where the given pc is.
(cplus_demangle): Put single-quotes around demangled names.

* config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
* serial.h (EXFUN): Remove all uses, convert to PARAMS.

treat as alias for TYPE_CODE_STRUCT for now.
(supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
Use "regi" for local indexing through register numbers, reserving
"regno" for the name of a specific register passed as an input
parameter. Fix bug propagated through all versions that sometimes
used regno as an index when it should have been regi, thus using
-1 as an index in some cases.

followed by pointer into string being demangled, followed by
pointer to the string where the result is being stored, followed
by other args. Also generally replace most variables of name

(2) extraneous line breaks introduced in some examples, sometimes
in ridiculously long strings; this may falsify examples. Places
where I did this are marked by FIXME comments.

* serial.c (find_source_lines): if LSEEK_NOT_LINEAR is defined
then work out the lseek positions of newlines by running through

* symtab.c (lookup_symbol, lookup_demangled_block_symbol,
lookup_demangled_partial_symbol,): Ask demangle_and_match to
match on complete demanglings, including argument lists for member

take advantage of gcc's builtin functions for increased performance.
