Summary:
This patch prevents reflowing bullet lists in block comments.
It handles all lists supported by doxygen and markdown, e.g. bullet
lists starting with '-', '*', '+', as well as numbered lists starting
with -# or a number followed by a dot.

Summary:
r303415 changed the way a sequence of line comments following a preprocessor
macro is handled, which has the unfortunate effect of aligning a trailing
preprocessor line comment and following unrelated section comments, so:
```
#ifdef A // comment about A
// section comment
#endif
```
gets turned into:
```
#ifdef A // comment about A
// section comment
#endif
```
This patch fixes this by additionally checking the original start columns of
the line comments.

Summary:
Doxygen supports putting documentation blocks after member, by adding
an additional < marker in the comment block. This patch makes sure
this marker is used in lines which are introduced by breaking the
comment.
int foo; ///< Some very long comment.
becomes:
int foo; ///< Some very long
///< comment.

Summary: This patch replaces the boolean IncompleteFormat that is used to notify the client if an unrecoverable syntax error occurred by a struct that also contains a line number.

Previously, if an escaped newline was followed by a newline or a nul, we'd lex
the escaped newline as a bogus space character. This led to a bunch of
different broken corner cases:
For the pattern "\\\n\0#", we would then have a (horizontal) space whose
spelling ends in a newline, and would decide that the '#' is at the start of a
line, and incorrectly start preprocessing a directive in the middle of a
logical source line. If we were already in the middle of a directive, this
would result in our attempting to process multiple directives at the same time!
This resulted in crashes, asserts, and hangs on invalid input, as discovered by
fuzz-testing.
For the pattern "\\\n" at EOF (with an implicit following nul byte), we would
produce a bogus trailing space character with spelling "\\\n". This was mostly
harmless, but would lead to clang-format getting confused and misformatting in
rare cases. We now produce a trailing EOF token with spelling "\\\n",
consistent with our handling for other similar cases -- an escaped newline is
always part of the token containing the next character, if any.
For the pattern "\\\n\n", this was somewhat more benign, but would produce an
extraneous whitespace token to clients who care about preserving whitespace.
However, it turns out that our lexing for line comments was relying on this bug
due to an off-by-one error in its computation of the end of the comment, on the
slow path where the comment might contain escaped newlines.

Those blocks are used if C++ code is SWIG-wrapped (see swig.org) and
usually do not contain C++ code. Also cleanup the implementation of for #if 0
and #if false a bit.

Summary: With a growing suite of comment-related tests, it makes sense to take them out of the main test file. No functional changes.
