The old API had (bool-vector-count-matches A B)
and (bool-vector-count-matches-at A B I), which gave the
misleading impression that the two functions were variants, one
with a location I. The new API has (bool-vector-count-population A)
and (bool-vector-count-consecutive A B I) to make the distinction
clearer. The first function no longer has a B argument, since the
caller can easily determine the number of nils if the length and
number of ts is known.
* src/data.c (Fbool_vector_count_population): Rename from
bool_vector_count_matches, and accept just 1 argument.
(Fbool_vector_count_consecutive): Rename from
Fbool_vector_count_matches_at.
* test/automated/data-tests.el: Adjust to API changes.

Rename from org-babel-python-with-earmufs. All uses changed.
(org-babel-python-without-earmuffs):
Rename from org-babel-python-without-earmufs. All uses changed.
* src/lisp.h (DEBUGGER_SEES_C_MACROS): Likewise.
It apparently doesn't work for GCC 3, and I suppose it's more
trouble than it's worth to worry about this.
* src/lisp.h (DEFINE_GDB_SYMBOL_BEGIN, DEFINE_GDB_SYMBOL_END):
Define to empty if DEBUGGER_SEES_C_MACROS is defined.
This avoids placing unnecessary constants into the Emacs code.

Simplify by using bool_vector_bytes.

if long long versions don't exist.

Simplify and tune.
* src/lisp.h (bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD):

(Fset_buffer_modified_p): Use them.
(syms_of_buffer): Defsubr Fforce_mode_line_update.
This avoids undefined behavior when subtracting pointers into
different aways. On my platform it also makes the code a tad
smaller and presumably faster.
* src/keyboard.c (command_loop_1): Use region-extract-function.
* src/insdel.c (Qregion_extract_function): Not static any more (can we
stop pretending that these vars can benefit from being marked static?).
* src/xfaces.c (lface_fully_specified_p): Let distant-foreground be
unspecified.
(realize_default_face): Remove assignment to distant-foreground if
unspecified.

cache-long-scans disabled, since we don't want to call
prepare_to_modify_buffer (in insert_1_both) for each message we
display.
src/buffer.h (bset_cache_long_scans): New INLINE function, moved
from buffer.c. Improve commentary to the buffer field setter

(Bug#15797)
This bug was introduced in my 2013-06-21 change, and caused
struct Lisp_Sub_Char_Table objects to be given too many slots,
which broke 'make -C admin/unidata'.

Fixes: debbugs:15802

string of glyphless-char-display.

unsigned char on unusual architectures, so that we no longer
assume that the number of bits per bits_word is a power of two or
is a multiple of 8 or of CHAR_BIT.
