This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
The binding <Alt + p, Shift + Return> is already used for
environment-split outer, so we bind <Alt + p, Alt + Return>
to environment-split before.

The log file generated by latex can contain strings encoded in
whatever supported encoding. Instead of guessing the encoding,
it is better to open it in binary mode and then performing the
necessary comparisons as "bytes". In order to do this, the
strings are encoded in utf8, so that, for example, b"pythön" is
encoded as "pyth\xc3\xb6n" (7 bytes). Of course, this means that
we can only successfully perform comparisons with ascii strings.
However, this is what we actually do, as we only search for
ascii strings in the log file.

Unfortunately, stat.st_ino returns 0 on Windows, at least on Python 2.7, so we can't use that way of telling when we're seeing the same directory again. Surely the real pathname should work.

Prevent that another processor (such as xindy) is used when set in prefs.
xindy does not play well with hyperref.

In python 3 the colors need to be strings and not bytes:
This was the equivalent of
>> print("%s" % b"1")
"b'1'"
since the colors were bytes the call to dvipng was something like
dvipng -Ttight -depth -height -D 115 -fg "b'rgb 0.937255 0.941176 0.945098'" -bg "b'rgb 0.137255 0.149020 0.160784'" "lyxpreviewxBJEqm.dvi"
Note the "b'rgb after both -fg and -bg that wrecked havoc and thus dvipng failed. That was the difference between python2 and python3 calls.

Loading keyval does not work any longer. Fix it properly by de-activating
the equal character locally if graphics options use it.
We do this statically for Turkish and Latin in stable, as opposed to
master (where we have the ActiveChars languages tag)
Nix (https://nixos.org) is a Unix package manager, which can be used to
install LaTeX on macOS. A peculiarity of Nix is that all packages are
installed into separate directories and the actual directory tree is
then constructed via symlinks.
This interacts badly with the way LyX currently detects files in the
TeX setup, because TeXFiles.py does not follow symlinks. Therefore,
almost nothing is found when using LyX together with Nix’ LaTeX.

The "Rows & Columns" optional submenu is more easily accessible in
the math context menu rather having to navigate to the "Edit" menu.
All possible accelerators are already taken, so use the space bar.

Same for BackTab. The outline-in was originally (31398779)
introduced to the command-sequence at the end. Probably it was
placed at the end to be conservative (i.e., so that it would only
change behavior where there was a no-op before).
This fixes#11576.
