2853a838d2 [clang-format] Add option to remove leading blank lines (#91221)
The options regarding which blank lines are kept are also aggregated.
The new option is `KeepEmptyLines`.

This patch was initially part of 9267f8f19a2e502e.  I neglected to check
the server builds before I added it.  It broke clangd.  Jie Fu fixed the
problem in 4c91b49bab0728d4.  I was unaware of it.  I thought the main
branch was still broken.  I reverted the first patch in
70cfece24d6cbb57.  It broke his fix.  He reverted it in
c69ea04fb9738db2.  Now the feature is added again including the fix.

I changed a formatter option.  I forgot to update other components that
depend on the formatter when the option name changed.

[clang-format] Stop aligning the to continuation lines (#76378)
Some unwrapped lines are marked as continuations of the previous lines,
for example the ports in a Verilog module header. Previously, if the
first line following the ports line was changed, and git-clang-format
was run, the changed line would be indented by an extra continuation
indentation.

[ClangFormat] Fix formatting bugs. (#76245)
1. There are multiple calls to addFakeParenthesis; move the guard to not
   assign fake parenthesis into the function to make sure we cover all
   calls.
2. MustBreakBefore can be set on a token in two cases: either during
   unwrapped line parsing, or later, during token annotation. We must
   keep the latter, but reset the former.
3. Added a test to document that the intended behavior of preferring not
   to break between a return type and a function identifier.
   For example, with MOCK_METHOD(r, n, a)=r n a, the code
   MOCK_METHOD(void, f, (int a, int b)) should prefer the same breaks as
   the expanded void f(int a, int b).

0570cc568f [clang-format] Fix indent for selective formatting
The problem was that the LevelIndentTracker remembered
the indentation level of previous deeper levels when
leaving a scope. Afterwards, when it entered again a
deeper level, it blindly reused the previous
indentation level. In case the --lines option was used
such that the previous deeper level was not formatted,
that previous level was whatever happened to be there
in the source code. The formatter simply believed it.

This is fixed by letting the LevelIndentTracker forget
the previous deeper levels when stepping out of them
(=> change in LevelIndentTracker::nextLine()).
Note that this used to be the case until LLVM 14.0.6,
but was changed in https://reviews.llvm.org/D129064

reverts that crash fix. It was incorrect/incomplete.

[clang-format] Ignore first token when finding MustBreak
When in ColumnLimit 0, the formatter looks for MustBreakBefore in the
line in order to check if a line is allowed to be merged onto one line.

However, since MustBreakBefore is really a property of the gap between
the token and the one previously, I belive the check is erroneous in
checking all the tokens in a line, since whether the previous line ended
with a forced line break should have no effect on whether the current
line is allowed to merge with the next one.

This patch changes the check to skip the first token in
`LineJoiner.containsMustBreak`.

This patch also changes a test, which is not ideal, but I believe the
test also suffered from this bug. The test case in question sets
AllowShortFunctionsOnASingleLine to "Empty", but the empty function in
said test case isn't merged to a single line, because of the very same
bug this patch fixes.

[clang-format] Rewrite how indent is reduced for compacted namespaces
The previous version set the indentation directly using IndentForLevel,
however, this has a few caveats, namely:

* IndentForLevel applies to all scopes of the entire program being
  formatted, but this indentation should only be adjusted for scopes
  of namespaces.

* The method it used only set the correct indent amount if one wasn't
  already set for a given level, meaning it didn't work correctly if
  anything with indentation preceded a namespace keyword. This
  includes preprocessing directives if using IndentPPDirectives.

This patch instead reduces the Level of all lines within namespaces
which are compacted by CompactNamespaces. This means they will get
correct indentation using the normal process.
