Add support for large files, 64-bit Solaris, system locale codings.

* Makefile.in (emacs): Set the LC_ALL environment variable to "C"
when dumping, so that the dumped Emacs doesn't have stray locale info.
(dired.o): Depend on systime.h.
(editfns.o): Depend on coding.h.

* alloc.c, buffer.c, callproc.c, ccl.c, charset.c, coding.c, data.c,
dispnew.c, editfns.c, emacs.c, filelock.c, floatfns.c, hftctl.c,
keyboard.c, process.c, sysdep.c, unexelf.c, unexhp9k800.c,
unexsunos4.c, vmsfns.c, vmsgmalloc.c, w32faces.c, w32menu.c, w32term.c,
w32xfns.c, xfaces.c, xfns.c, xmenu.c, xterm.c:
Include <config.h> before any system include files.

* alloc.c, buffer.c, ccl.c, data.c, editfns.c, emacs.c, eval.c,
fileio.c, filelock.c, frame.c, insdel.c, keymap.c, lread.c,
m/alpha.h, print.c, search.c, sysdep.c, xdisp.c, xfaces.c, xfns.c,
xmenu.c, xterm.c:
Do not include <stdlib.h>, as <config.h> does this now.

* callproc.c (Fcall_process):
Synchronize messages locale before invoking strerror.
Decode resulting string with locale-coding-system.

* coding.c (Vlocale_coding_system): New var.
(syms_of_coding): Adjust to above change.
(emacs_strerror): New function.

* coding.h (emacs_strerror, Vlocale_coding_system): New decls.

* config.in (HAVE_STDIO_EXT_H, HAVE_TM_GMTOFF, HAVE___FPENDING,
HAVE_FTELLO, HAVE_GETLOADAVG, HAVE_MBLEN, HAVE_MBRLEN,
HAVE_STRSIGNAL): New macros.
(BITS_PER_LONG): Default to 64 if _LP64 is defined.
<stdlib.h>: Include if HAVE_STDLIB_H is defined and NOT_C_CODE isn't.

* dired.c: Include "systime.h".
(Ffile_attributes): Do not cast s.st_size to int; this loses
information if int is 32 bits but st_size and EMACS_INT are larger.
Treat large device numbers like large inode numbers.

* dispnew.c (PENDING_OUTPUT_COUNT): Use __fpending if available.

* editfns.c: Include coding.h.
(emacs_strftime): Remove decl.
(emacs_strftimeu): New decl.
(emacs_memftimeu): Renamed from emacs_memftime; new arg UT.
Use emacs_strftimeu instead of emacs_strftime.
(Fformat_time_string): Convert format string using
Vlocale_coding_system, and convert result back.  Synchronize time
locale before invoking lower level function.  Invoke
emacs_memftimeu, passing ut, instead of emacs_memftime.

* emacs.c: Include <locale.h> if HAVE_SETLOCALE is defined.
(Vmessages_locale, Vprevious_messages_locale, Vtime_locale,
Vprevious_time_locale): New variables.
(main): Invoke setlocale early, so that initial error messages are
localized properly.  But skip locale-setting if LC_ALL is "C".
Fix up locale when it's safe to do so.
(fixup_locale): Moved here from xterm.c.
(synchronize_locale, synchronize_time_locale,
synchronize_messages_locale): New functions.
(syms_of_emacs): Accommodate above changes.

* fileio.c (report_file_error): Convert strerror output according
to Vlocale_coding_system.
(Finsert_file_contents): Check for arithmetic overflow in
computations that depend on file size.  Report IO errors
with emacs_strerror, not strerror.

* fns.c (Fgethash): Declare dflt parameter.

* gmalloc.c: Do not define const to nothing if HAVE_CONFIG_H
is defined; that's config.h's job.

* lisp.h (EMACS_INT, BITS_PER_EMACS_INT, EMACS_UINT): If _LP64,
default these values to long, BITS_PER_LONG, and unsigned long.
(VALBITS, MARKBIT, XINT): Do not assume 32-bit EMACS_INT.
(PNTR_COMPARISON_TYPE): Default to EMACS_UINT, not to unsigned int.
(code_convert_string_norecord, fixup_locale,
synchronize_messages_locale, synchronize_time_locale,
emacs_open, emacs_close, emacs_read, emacs_write): New decls.
All Emacs callers of open, close, read, write changed to use
emacs_open, emacs_close, emacs_read, emacs_write.

* lread.c (file_offset, file_tell): New macros.  All uses of ftell
changed to file_tell.
(saved_doc_string_position, prev_saved_doc_string_position): Now
of type file_offset.
(init_lread): Do not fix locale here; fixup_locale now does this.

* m/amdahl.h, s/usg5-4.h:
(NSIG): Remove.
(NSIG_MINIMUM): New macro.

* m/cydra5.h, m/dpx2.h, m/mips.h, m/pfa50.h, m/sps7.h, m/stride.h,
m/ustation.h, s/gnu-linux.h, s/hpux.h, s/iris3-5.h, s/iris3-6.h,
s/umips.h, s/usg5-4.h:
(SIGIO): Do not undef.
(BROKEN_SIGIO): New macro.

* m/ustation.h:
(SIGTSTP): Do not undef.
(BROKEN_SIGTSTP): New macro.

* s/gnu-linux.h:
(SIGPOLL, SIGURG): Do not undef.
(BROKEN_SIGPOLL, BROKEN_SIGURG): New macros.

* s/ptx4.h:
(SIGINFO): Do not undef.
(BROKEN_SIGINFO): New macros.

* m/delta.h, s/ptx.h, s/template.h: Doc fix.

* mktime.c, strftime.c: Update to glibc 2.1.2 version, with
some Emacs-related changes merged.

* print.c (float_to_string): Prepend "-" to representation of a
NaN if the NaN is negative.

* process.c (sys_siglist): Omit if HAVE_STRSIGNAL.
(wait_reading_process_input): Use emacs_strerror, not strerror.

* process.c (status_message, sigchld_handler): Synchronize locale,
then use strsignal istead of sys_siglist.
* w32proc.c (sys_wait): Likewise.

* s/aix3-1.h, s/bsd4-1.h, s/dgux.h, s/gnu-linux.h, s/hiuxmpp.h,
s/hpux.h, s/iris3-5.h, s/iris3-6.h, s/irix3-3.h, s/osf1.h, s/rtu.h,
s/sunos4-1.h, s/unipl5-0.h, s/unipl5-2.h, s/usg5-0.h, s/usg5-2-2.h,
s/usg5-2.h, s/usg5-3.h, s/xenix.h:
(open, close, read, write, INTERRUPTIBLE_OPEN,
INTERRUPTIBLE_CLOSE, INTERRUPTIBLE_IO): Remove.

* s/sol2-5.h (_LARGEFILE_SOURCE, _FILE_OFFSET_BITS): New macros.
* sysdep.c (sys_read, sys_write, read, write, sys_close, close,
sys_open, open): Remove.
(emacs_open, emacs_close, emacs_read, emacs_write): Always define;
the old INTERRUPTIBLE_OPEN, INTERRUPTIBLE_CLOSE, and INTERRUPTIBLE_IO
macros are no longer used.
(emacs_open): Renamed from sys_open.  Merge BSD4_1 version.
(emacs_close): Renamed from sys_close.
(emacs_read): Renamed from sys_read.
(emacs_write): Renamed from sys_write.
(sys_siglist): Do not declare if HAVE_STRSIGNAL.
(dup2): Do not print error on failure; the real dup2 doesn't.
(strsignal): New function, defined if !HAVE_STRSIGNAL.

* syssignal.h (SIGINFO): Undef if defined and if BROKEN_SIGINFO
is defined.
(SIGIO, SIGPOLL, SIGTSTP, SIGURG): Likewise.
(NSIG): If less than NSIG_MINIMUM, define to NSIG_MINIMUM.
(strsignal): Declare if !HAVE_STRSIGNAL.

* unexelf.c (ElfBitsW, ELFSIZE, ElfExpandBitsW): New macros.
(ElfW): Define in terms of ElfExpandBitsW.

* w32proc.c (sys_siglist): Remove decl.

* xdisp.c (decode_mode_spec): 3rd arg is int, not char, to comply
with ANSI C.
(display_string): Declare face_string_pos arg.

* xfns.c (Fx_show_tip): Declare timeout param.

* xterm.c: No need to include locale.h.
(x_alloc_lighter_color, x_setup_relief_color):
Pass arg as double, not float, for compatibility with ANSI C.
(fixup_locale): Move to emacs.c.
(x_term_init): Do not setlocale or fixup locale; the main program
does this now.
