Getting the statusbar context ID using the context registration API
allows for other (namely, plugins) to register their own context
without a risk of overriding Geany's one.
Although using menu items for these is not very practical, it helps
discoverability, and they're more useful and intuitive than 'Transpose
Current Line'.
This copies the current document text and properties into a new
document, similar to the old Save As 'Open file in a new tab'
option, but easier to understand and decoupled from saving.
One notable difference is that the new document does not copy the
filename - the old behaviour was confusing and error-prone for the
user (e.g. editing two documents with the same filename).
We were improperly adding the printing device margins to the area
where we print, leading to wider margins on physical outputs than
on PDF or preview outputs (which have no hard margins), as well as
wasting space and not respecting user's settings.

This prevents a regex pattern from fooling the parser if it contains
some recognized constructs, like comment or string literal starts.
Closes#2992393 and #3398636.
Build command spawning failed sometimes when there were several
pages of errors. In these cases the process would block for 30s and
then abort. (Some hangs were also experienced).
This fix does cause a console window to be shown for the duration of
the spawned process. This seems acceptable compared with the old
broken behaviour, and can be useful to abort the build command by
closing the console window.
Note: If 'env' is passed, the old broken spawning is used.
If a title contained multi-byte UTF-8 characters, it wasn't properly
recognized due to the title being longer (in bytes) than the underline.
So, fix the title length computation to properly count the characters,
not the bytes.
Note that this fix only handles ASCII, one-byte charsets and UTF-8, it
won't help with other multi-bytes encodings. However, the whole parser
expects ASCII-compatible encoding anyway, and in most situations it
will be fed the Geany's UTF-8 buffer.
Closes#3578050.
