isnan: Fix porting problem to Solaris 10 with bundled gcc.

Without this fix, the command to link temacs failed due to an
undefined symbol __builtin_isnan.  This is because
/usr/include/iso/math_c99.h #defines isnan(x) to
__builtin_isnan(x), but the bundled gcc, which identifies itself
as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
a __builtin_isnan.
* configure.in (isnan): Remove now-unnecessary check.
* src/floatfns.c (isnan): #undef, and then #define to a clone of
what's in data.c.

continue to delete remaining escape sequences from the same point.
(grep-filter): Make leading zero optional in "0?1;31m" because
git-grep emits "\033[1;31m" escape sequences unlike expected

values converted from Emacs fixnums.
(Frecenter): Don't wrap around a line count if it is out of 'int'
range; instead, treat it as an extreme value.

Use ptrdiff_t, not int, for index that might exceed 2 GiB.

 lisp/mail/rmailmm.el (rmail-mime-insert-tagline): Insert an extra

 with determining the paragraph direction of bidirectional text.

* fileio.c: Fix bugs with large file offsets.

The previous code assumed that file offsets (off_t values) fit in
EMACS_INT variables, which is not true on typical 32-bit hosts.
The code messed up by falsely reporting buffer overflow in cases
such as (insert-file-contents "big" nil 1 2) into an empty buffer
when "big" contains more than 2**29 bytes, even though this
inserts just one byte and does not overflow the buffer.
(Finsert_file_contents): Store file offsets as off_t
values, not as EMACS_INT values.  Check for overflow when
converting between EMACS_INT and off_t.  When checking for
buffer overflow or for overlap, take the offsets into account.
Don't use EMACS_INT for small values where int suffices.
When checking for overlap, fix a typo: ZV was used where
ZV_BYTE was intended.
(Fwrite_region): Don't assume off_t fits into 'long'.
* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

Remove unused variable find-file-not-true-dirname-list
