1) utils_strv_find_common_prefix
Locates the common prefix.

2) utils_strv_find_lcs
Finds the longest common substring.

3) utils_strv_shorten_file_list
Transforms the file list by removing the common prefix and ellipsizing
the longest common substring. This is intended to be used for fixing #1069.

Although only 3 will be used immediately, I separated the functionality, so
that the other two function can be used on their own.

This uses a menu and is thus subject to the menu icons visibility
setting, but here it should reflect the view from the symbols list,
and thus show the icon in all cases.

Use REM as single comment marker for Batch files

Windows: Enable DPI-aware mode in Windows Assembly Manifest

Update std.php.tags to be current with PHP 7.2

Fixes #1958 

Also replace GDK_space with ASCII space, its searching for that, not the keycode (which just happens to have the same value, lucky).

This should solve display issues with HiDPI displays.
Closes #692.

Process files in the order they appear on the command line when
generating tags file, instead of a more or less random order.

Closes #1989.

Don't use the files inode as the hash.  Although it looks like a good
idea for de-duplicating links as well, it has several issues, including
non-uniqueness of inodes across file systems.
The way it was done hashing the inode but comparing the file name
string pointers also made the hash mostly irrelevant, as it just stored
filenames sharing the same inode in the same hash bucket but without
actually doing any de-duplication, making the whole thing a convoluted
way of converting to a list.

Instead, hash and compare the filenames themselves, which, even though
it doesn't handle links de-duplication, is better than the
non-functional previous code.

Also, directly build the list and only use the hash table as a way for
checking for duplicates, which is both faster and gives a stable
output.

Update link to GTK+3 bundle for test builds to self-hosted version

Update Scintilla to version 3.10.0

Fixes #1421.

REM seems to be the standard comment marker while "::" is rather
deprecated.

Closes #1912.

The host win32builder.gnome.org seems dead and so host the GTK+3 bundle
we use to test builds for Windows cross-compilation on our own.

Pango now requires fribidi, so we need to install it.
Update the download URL for UnxUtils.
Remove unnecessary cmake files after installation.

Update Python identifiers with Python 3.7

Now the keybinding can be overridden (e.g. using Tab for it as well as
normal behavior), beeping when there is no next cursor is more annoying
than useful.

Part of #1554.

The new styles are for "diff of a diff", e.g. lines starting with `++`,
`+-`, `-+` and `--`.  Those are currently mapped conservatively keeping
the previous display behavior, until we have good style matches for
them.

Scintilla 3.7.6/4.0.0 deprecated `SCE_*STYLEBITS*` and moved it to
deprecated features that require a build-time flag to be available.

Thus, drop use of those (as they are now no-ops anyway) and bump the
ABI (so plugins depending on those don't build mistakenly load) and API
(so a developer can guard use of those if wanted) version accordingly.

These two strings have probably been translated with a generic online tool which lacks of contextual translation

Fixes #395.
