Adam Czachorowski 9108715321 [clangd] Fix AddUsing tweak for out-of-line functions.
Summary:
We used getEnclosingNamespaceContext(), which calls getParent() rather
than getLexicalParent(), so we would end up adding the "using" line in
places that do not affect the cursor location, or just return an error
when declaration was in another file.

Patch by Adam Czachorowski!

Summary:
Added `DiagnoseSignedUnsignedCharComparisons` option to
filter out unrelated use cases. The SEI cert catches explicit
integer casts (two use cases), while in the case of
`signed char` \ `unsigned char` comparison, we have implicit
conversions.

Dmitri Gribenko 3adaa97f01 Fix ForRangeCopyCheck not triggering on iterators returning elements by value in C++17.
Summary:
The AST is different in C++17 in that there is no MaterializeTemporaryExpr for in the AST for a loop variable that is initialized from an iterator that returns its elements by value.

Account for this by checking that the variable is not initialized by an operator* call that returns a value type.

Konrad Kleine 24b4965ce6 [clang/clang-tools-extra] Fix BZ44437 - add_new_check.py does not work with Python 3
Summary:
This fixes https://bugs.llvm.org/show_bug.cgi?id=44437.

Thanks to Arnaud Desitter for providing the patch in the bug report!

A simple example program to reproduce this error is this:

```lang=python

import sys

with open(sys.argv[0], 'r') as f:
  lines = f.readlines()
lines = iter(lines)
line = lines.next()
print(line)
```

which will error with this in python python 3:

```
Traceback (most recent call last):
  File "./mytest.py", line 8, in <module>
    line = lines.next()
AttributeError: 'list_iterator' object has no attribute 'next'
```

Here's the same strategy applied to my test program as applied to the `add_new_check.py` file:

```lang=python

import sys

with open(sys.argv[0], 'r') as f:
  lines = f.readlines()
lines = iter(lines)
line = next(lines)
print(line)
```

The built-in function `next()` is new since Python 2.6: https://docs.python.org/2/library/functions.html#next

For document links we make use of the spelledtokens stored in tokenbuffers to

For go-to-def, we keep storing the line number we've seen the include directive.

Tamás Zolnai 030ff901f4 [clang-tidy] extend bugprone-signed-char-misuse check with array subscript case.
Summary:
To cover STR34-C rule's second use case, where ``signed char`` is
used for array subscript after an integer conversion. In the case
of non-ASCII character this conversion will result in a value
in excess of UCHAR_MAX.

There is another clang-tidy check which catches these cases.
cppcoreguidelines-pro-bounds-constant-array-index catches any
indexing which is not integer constant. I think this check is
very strict about the index (e.g. constant), so it's still useful
to cover the ``signed char`` use case in this check, so we
can provide a way to catch the SEI cert rule's use cases on a
codebase, where this CPP guideline is not used.

Vojtěch Štěpančík ad38f4b371 Add a facility to get system cache directory and use it in clangd
Summary:
This patch adds a function that is similar to `llvm::sys::path::home_directory`, but provides access to the system cache directory.

For Windows, that is %LOCALAPPDATA%, and applications should put their files under %LOCALAPPDATA%\Organization\Product\.

For *nixes, it adheres to the XDG Base Directory Specification, so it first looks at the XDG_CACHE_HOME environment variable and falls back to ~/.cache/.

Subsequently, the Clangd Index storage leverages this new API to put index files somewhere else than the users home directory.

[clangd] Fix remote index build without shared libs mode
Summary:
Generated Protobuf library has to be in CLANG_EXPORTS and should also be
installed appropriately. The easiest way to do that is via CMake's
add_clang_library. That unfortunately applies "one directory - one
clang_(library|tool)" policy so .proto files should be in a separate directory
and complicates the layout.

This setup works both in shared and static libs mode.
