as required per core issue 1552 and warned about with
-Wimplicit-exception-spec-mismatch.

Dmitry Vyukov 8aaa44c43d tsan: relax check for errno spoiling more
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

Alexander Potapenko d5802fe548 Make signal-related functions use __sanitizer_* structures instead of __sanitizer_kernel_* ones.
Also rename internal_sigaction() into internal_sigaction_norestorer(), as this function doesn't fully
implement the sigaction() functionality on Linux.

This change is a part of refactoring intended to have common signal handling behavior in all tools.

Dmitry Vyukov 7c9621c0be tsan: relax checking of errno spoiling in signal handlers

Dmitry Vyukov 1b3862ab06 tsan: fix signal handling
We left ignore_interceptors>0 when calling signal handlers
from blocking interceptors, this leads to missing synchronization in such signal handler.

Dmitry Vyukov 16e7a758b0 tsan: do not deadlock on fork
Currently correct programs can deadlock after fork, because atomic operations and async-signal-safe calls are not async-signal-safe under tsan.
With this change:
- if a single-threaded program forks, the child continues running with verification enabled (the tsan background thread is recreated as well)
- if a multi-threaded program forks, then the child runs with verification disabled (memory accesses, atomic operations and interceptors are disabled); it's expected that it will exec soon anyway
- if the child tries to create more threads after multi-threaded fork, the program aborts with error message
- die_after_fork flag is added that allows to continue running, but all bets are off

Dmitry Vyukov ce3721057d tsan: remove in_rtl counter
This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

Dmitry Vyukov 5ba736457c tsan: ignore interceptors coming from specified libraries
LibIgnore allows to ignore all interceptors called from a particular set
of dynamic libraries. LibIgnore remembers all "called_from_lib" suppressions
from the provided SuppressionContext; finds code ranges for the libraries;
and checks whether the provided PC value belongs to the code ranges.

Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of
SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib,
then must call our internal allocator instead of libc malloc.
