Flymake backends can report multiple times per check
Rewrote a significant part of the Flymake backend API. Flymake now
ignores the return value of backend functions: a function can either
returns or errors. If it doesn't error, a backend is no longer
constrained to call REPORT-FN exactly once. It may do so any number
of times, cumulatively reporting diagnostics. Flymake keeps track of
outdated REPORT-FN instances and disconsiders obsolete reports.
Backends should avoid reporting obsolete data by cancelling any
ongoing processing at every renewed call to the backend function.
Consolidated flymake.el internal data structures to require less
buffer-local variables. Adjusted Flymake's mode-line indicator to the
new semantics.

Fix three Flymake bugs when checking C header files
The first of these problems is longstanding: if an error-less B.h is
included from error-ridden A.h, flymake's legacy parser will panic
(and disable itself) since it sees a non-zero exit for a clean file.
To fix this, recommend returning 'true' in the documentation for the
check-syntax target.
Another problem was introduced by the parser rewrite. For error
patterns spanning more than one line, point may be left in the middle
of a line and thus render other patterns useless. Those patterns were
written for the old line-by-line parser. To make them useful again,
move to the beginning of line in those situations.
The third problem was also longstanding and happened on newer GCC's:

line less often.

New Flymake API variable flymake-diagnostic-functions
Lay groundwork for multiple active backends in the same buffer.
Backends are lisp functions called when flymake-mode sees fit. They
are responsible for examining the current buffer and telling
flymake.el, via return value, if they can syntax check it.
Backends should return quickly and inexpensively, but they are also
passed a REPORT-FN argument which they may or may not call
asynchronously after performing more expensive work.
REPORT-FN's calling convention stipulates that a backend calls it with
a list of diagnostics as argument, or, alternatively, with a symbol
denoting an exceptional situation, usually some panic resulting from a
misconfigured backend. In keeping with legacy behaviour,
flymake.el's response to a panic is to disable the issuing backend.
The flymake--diag object representing a diagnostic now also keeps
information about its source backend. Among other uses, this allows
flymake to selectively cleanup overlays based on which backend is
updating its diagnostics.

Diagnostics are reported for buffers, not necessarily files. It’s the

Flymake diagnostics now apply to arbitrary buffer regions

manipulating objects representing diagnostics as well as creating and

Lay some groundwork for a more flexible approach that allows for
different classes of diagnostics, not necessarily line-based.
Importantly, one overlay per diagnostic is created, whereas the
original implementation had one per line, and on it it concatenated
the results of errors and warnings.
This means that currently, an error and warning on the same line are
problematic and the warning might be overlooked but this will soon be
fixed by setting appropriate priorities.
Since diagnostics can highlight arbitrary regions, not just lines, the

Revert "Split flymake.el into flymake-proc.el and flymake-ui.el"
In other words, re-coalesce the two files,
lisp/progmodes/flymake-proc.el and lisp/progmodes/flymake-ui.el, back
into a single one, lisp/progmodes/flymake.el.
The changesets "Prefer HTTPS to FTP and HTTP in documentation" and
"allow nil init in flymake-allowed-file-name-masks to disable flymake"
are kept in place in the new lisp/progmodes/flymake.el.

Avoid some unnecessary copying in Fformat etc.
This patch is just for performance; it should not affect behavior.
On my platform, it made the microbenchmark (format "%S" load-path)
run about 45% faster. It should also speed up calls like (message
"%s" STRING).

* src/dbusbind.c (XD_OBJECT_TO_STRING):
* src/editfns.c (Fmessage, Fmessage_box):
* src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
Use styled_format instead of Fformat or Fformat_message,
to avoid unnecessary copying.
* src/editfns.c (styled_format): New arg NEW_RESULT.
All uses changed. Reuse an input string if it has the
right value and if !NEW_RESULT.
* src/lisp.h (style_format): New decl.

* lisp/emacs-lisp/syntax.el (syntax-ppss-wide):
