See the discussion. The decision was just to keep re-trying for a
bit, since the lock preventing us from removing the old file seems
to clear after a bit.

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.
Patch from Michael Roitzsch.

Do not replace a latex command with the corresponding symbol
in the unicodesymbols file unless it can be encoded in the
document encoding.
The mhchem \ce inset is a text mode environment but allows entering
spaces and mathmode commands. However, even if it doesn't allow unicode
symbols, LyX allows entering them (by copy/paste, for example), causing
latex errors. As a unicode symbol may have a proper latex representation
from the unicodesymbols file, use it instead of the bare symbol. Here, we
don't care about the mode because both text and math mode should be allowed.
For example, the ⟶ symbol is not recognized but its latex representation
(\longrightarrow) is fine. Of course, there may be symbols that are
not recognized anyway, but this is better because they cause explicit
errors from mhchem instead of cryptic iconv errors in case they cannot
be represented in the document encoding.
A branch inset modifies the layout of the internal structures in
which the text is organized. When a branch is active, it is as if it
was not there, but its only presence makes a paragraph which would not
be the last one to actually be the last one, or the check for the
language of the previous paragraph to fail because there is no
previous paragraph before the first one in a branch inset.
Oney way I found to tackle it, is tracking whether the typesetted
paragraphs are actually part of an active branch inset and acting
accordingly.
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.

Avoid an endless loop when in the definition of a macro the macro
itself is used in the LyX representation part.

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.
(cherry picked from commit 9ab9f2b1ac)
The current heuristics only considered modules with styles that defined
a searched command in their preamble, and only for commands/environments
that were defined in the document's preamble. This limited the module
support drastically.
The new heuristics also checks for commands coming from packages. If the
command is not (re-)defined in the document preamble, it checks modules
that provide a style with a matching LaTeXName, checks for their
requirements and matches those with the packages loaded by the document.
If no module provides a searched style, but we found modules that load
packages that are loaded in the imported tex file, and if those packages
are not auto-loaded by LyX anyway, we also load this module.
fixes: #11259, part of #8229

This is a much less invasive version of da2696cc+da2696cc, which
reduces the risk to a minimum. There may be other Row members that
need resetting, we'll see that later.
Fixes bug #11396.
This is hardcoded for now for simplicity and to allow backporting to
2.3.
The behavior is unchanged for all languages but Chinese, Japanese or
Korean.
Fixes part of bug #10299.
