Add space around arithmetic operators '+' and '-'.

Add the following options to extmarks:
- sign_text
- sign_hl_group
- number_hl_group
- line_hl_group
- cursorline_hl_group
Note: ranges are unsupported and decorations are only applied to
start_row
marktree.c was originally constructed as a "generic" datatype,
to make the prototyping of its internal logic as simple as possible
and also as the usecases for various kinds of extmarks/decorations was not yet decided.
As a consequence of this, various extra indirections and allocations was
needed to use marktree to implement extmarks (ns/id pairs) and
decorations of different kinds (some which is just a single highlight
id, other an allocated list of virtual text/lines)
This change removes a lot of indirection, by making Marktree specialized
for the usecase. In particular, the namespace id and mark id is stored
directly, instead of the 64-bit global id particular to the Marktree
struct. This removes the two maps needed to convert between global and
per-ns ids.
Also, "small" decorations are stored inline, i.e. those who
doesn't refer to external heap memory anyway. That is highlights (with
priority+flags) are stored inline, while virtual text, which anyway
occurs a lot of heap allocations, do not. (previously a hack was used
to elide heap allocations for highlights with standard prio+flags)
TODO(bfredl): the functionaltest-lua CI version of gcc is having
severe issues with uint16_t bitfields, so splitting up compound
assignments and redundant casts are needed. Clean this up once we switch
to a working compiler version.
This allows to more quickly skip though regions which has non-decorative
marks when redrawing. This might seem like a gratuitous
micro-optimization in isolation.
But!
Soon decorations are gonna crop into other hot inner-loop paths,
including the plines.c code for calculating the horizontal and
vertical space of text. Then we want to quickly skip over regions with
"only" overlaying decorations (which do not affect text size)
* refactor: format all C files under nvim
* refactor: disable formatting for Vim-owned files:
* src/nvim/indent_c.c
* src/nvim/regexp.c
* src/nvim/regexp_nfa.c
* src/nvim/testdir/samples/memfile_test.c
This is inspired by Atom's "marker index" data structure to efficiently
adjust marks to text insertions deletions, but uses a wide B-tree
(derived from kbtree) to keep the nesting level down.
