Add and document more checkpatch message types. About 50% of all
message types are documented now.

In addition to this:

- Create a new subsection 'Indentation and Line Breaks'.
- Rename subsection 'Comment style' to simply 'Comments'.
- Refactor some of the existing types to appropriate subsections.

Andrew Jeffery 0e7c52da1a Documentation: checkpatch: Tweak BIT() macro include
While include/linux/bitops.h brings in the BIT() macro, it was moved to
include/linux/bits.h in commit 8bd9cb51da ("locking/atomics, asm-generic:
Move some macros from <linux/bitops.h> to a new <linux/bits.h> file").

Since that commit BIT() has moved again into include/vdso/bits.h via
commit 3945ff37d2 ("linux/bits.h: Extract common header for vDSO").

I think the move to the vDSO header can be considered an implementation
detail, so for now update the checkpatch documentation to recommend use
of include/linux/bits.h.

Dwaipayan Ray 3337c3a152 docs: document all error message types in checkpatch
All the error message types now have a verbose description.

Also there are two new groups of message types:

- Macros, Attributes and Symbols
- Functions and Variables

Rearrange the message types to fit these new groups as needed.
