Some classes provide a \bibliographystyle, so we must not output any
\bibliographystyle if none is set in the TeX file.

Add a `cancel' boolean to macroModeClose() that just removes all trace
of what has been entered instead of finalizing it.
When entering a macro in mathed, let LFUN_ESCAPE invoke
macroModeClose(true). The new semantics of LFUN_ESCAPE in mathed is
thus to abort the input of a macro name.
Fixes bug #9251.

As of v. 1.7.7, chktex has four exit values. Only consider the program
failed with EXIT_FAILURE (1). This is backwards compatible to chktex
up to v. 1.7.5 and later patched versions included in TeXLive, where
there was the distinction EXIT_FAILURE (program failed) and EXIT_SUCCESS
(program successfully run, with or without something to report).
Note that ChkTeX v. 1.7.5 and 1.7.6 vanilla (as included in MikTeX) also
returned EXITE_FAILURE if ChkTeX found something to report.
We do not, and never did, support this case.
Fixes: #9989 (after ChkTeX 1.7.7. is released).

Since CheckTeX itself processes the tex file, a synchronous run with
a TeX process can lead to all sorts of conflicts, including crashes.
Fixes: #7434.

I am rather irritated we didn't do this already, since synchronous runs
with BUFFER_VIEW or BUFFER_UPDATE leads to all sorts of problems,
including crashes.
Fixes the crash in #8338 (but not the bug itself).

This is needed for cases where the temp file has to be manually removed
at some point (e.g., if temp files are used as conversion target, and
the initial file only serves as a placeholder), since QTemporaryFile
objects cannot be manually removed at least on Windows (they are always
kept open internally even after close()). See
http://lists.qt-project.org/pipermail/interest/2013-August/008352.html
In order to avoid race conditions due to duplicate names (the issue why
the old method was removed), we record all used temp file names.
Fixes: #9139
