Kostya Kortchinsky b3a924afd6 [scudo][standalone] Add a standalone vector class
Summary:
This CL adds a standalone vector class that will be used by the scoped
strings when they land. We reimplement our own vector class because we
can't use the std library one.

It's mostly borrowed from the current sanitizer_common one, with LLVM
code style changes.

Additionnally a casing change in a function name that slipped through
the previous review (the function isn't used yet).

Kostya Kortchinsky 41aba567d9 [scudo][standalone] Introduce platform specific code & mutexes
Summary:
This CL adds the platform specific code for Fuchsia, Linux & Android,
as well as some tests related to those (more tests to come later).
While some of it is pretty much a straight port of the existing scudo &
sanitizer_common code, the memory mapping functions have been reworked
a bit to fit the limited usage scenario that Scudo has for them.

For Fuchsia, I can now track the Vmar/Vmo pair for memory mappings if
there is an intent to grow or decommit some mapping (that will be
useful for the Primary).

Jonas Hahnfeld a05d442391 [compiler-rt] Cleanup usage of C++ ABI library
Add missed value "libcxxabi" and introduce SANITIZER_TEST_CXX for linking
unit tests. This needs to be a full C++ library and cannot be libcxxabi.

Recommit r354132 which I reverted in r354153 because it broke a sanitizer
bot. This was because of the "fixes" for pthread linking, so I've removed
these changes.

Kostya Kortchinsky 7547170ca4 [scudo][standalone] Do not error out on spurious C(XX) flags
Summary:
The standalone Scudo version is being built with `-Werror` which can be
tripped by extraneous command line arguments. We have little control over
those as they can be passed down to us by `CMAKE_C(XX)_FLAGS`, the reported
scenario involving `-stdlib=libc++` (see https://reviews.llvm.org/D57412#1384504).

To work around this, disable `-Wunused-command-line-argument`.

Kostya Kortchinsky 47f0d136f1 [scudo] Initial standalone skeleton check-in
Summary:
This is the initial check-in for the Standalone version of Scudo.

The project is initially going to live in scudo/standalone then will
replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html
for details.

This initial CL is meant to lay out the project structure, of both
code & tests, providing a minimal amount of functionalities, namely
various definitions, some atomic helpers and an intrusive list.
(empty.cc is just here to have a compilation unit, but will go away
in the upcoming CLs).

Initial support is restricted to Linux i386 & x86_64 in make files
and will be extended once things land & work.

We will grow organically from here, adding functionalities in limited
amounts.
