Flymake backends that rely on sentinels running asynchronously and

Fix some confusing parts of Flymake user documentation, like a
repeated listing of situations leading to a syntax check.

Flymake", "Extending Flymake", and a chapter for the legacy backend.
Obsolete mention of "errors" and "lines" is replaced by
"diagnostics/problems" and "regions" where appropriate.

Although the Lisp manual said that ‘format’ returns a
newly-allocated string, this was not true for a few cases like
(format "%s" ""), and fixing the documentation to allow reuse of
arguments lets us improve performance in common cases like
(format "foo") and (format "%s" "foo") (Bug#28625).
* doc/lispref/strings.texi (Formatting Strings):
* etc/NEWS:
Say that the result of ‘format’ might not be newly allocated.

* src/dbusbind.c (XD_OBJECT_TO_STRING):
* src/editfns.c (Fmessage, Fmessage_box):
* src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
Just use Fformat or Fformat_message, as that’s simpler and no
longer makes unnecessary copies.
* src/editfns.c (styled_format): Remove last argument, as it
is no longer needed: all callers now want it to behave as if it
were true. All remaining callers changed. Make this function
static again. Simplify the function now that we no longer
need to worry about whether the optimization is allowed.

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:
The "In file included from" prefix confused
flymake-proc-get-real-file-name. Fix this.
Also updated flymake--diag-region to fallback to highlighting a full
line less often.
Add automatic tests to check this.
* lisp/progmodes/flymake-proc.el

* doc/misc/flymake.texi (Example---Configuring a tool called
via make): Recommend adding "|| true" to the check-syntax target.
