Unfortunately, we must restrict the checker to warn for deprecated headers
only if the header is included directly from a c++ source file.
For header files, we cannot know if the project has a C source file
that also directly/indirectly includes the offending header file
otherwise. Thus, it's better to be on the safe side and suppress those
reports.
One can opt-in the old behavior, emitting diagnostics into header files,
if one explicitly sets the WarnIntoHeaders=true, in which case nothing
will be changed.

This partially reverts commit e8cae48702.
Changes since that commit:
- Use `SourceManager::isBeforeInTranslationUnit` instead of the fancy
decomposed decl logarithmic search.
- Add a test for including a system header containing a deprecated
include.
- Add `REQUIRES: system-linux` clause to the test.

The check should not report includes wrapped by `extern "C" { ... }` blocks,
such as:
```lang=C++
#ifdef __cplusplus
extern "C" {
#endif
#include "assert.h"
#ifdef __cplusplus
}
#endif
```
This pattern comes up sometimes in header files designed to be consumed
by both C and C++ source files.
The check now reports false reports when the header file is consumed by
a C++ translation unit.
In this change, I'm not emitting the reports immediately from the
`PPCallback`, rather aggregating them for further processing.
After all preprocessing is done, the matcher will be called on the
`TranslationUnitDecl`, ensuring that the check callback is called only
once.
Within that callback, I'm recursively visiting each decls, looking for
`LinkageSpecDecls` which represent the `extern "C"` specifier.
After this, I'm dropping all the reports coming from inside of it.
After the visitation is done, I'm emitting the reports I'm left with.
For performance reasons, I'm sorting the `IncludeMarkers` by their
corresponding locations.
This makes the scan `O(log(N)` when looking up the `IncludeMarkers`
affected by the given `extern "C"` block. For this, I'm using
`lower_bound()` and `upper_bound()`.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
This patch introduces the modernize-deprecated-headers check, which is supposed to replace deprecated C library headers with the C++ STL-ones.
