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.
