[sanitizer] Adjust max read size in FlagHandlerInclude
...
Setting the maximum read size in FlagHandlerInclude to 2^15 might be a good
default, but causes the read to fail on systems with a page size larger than
that (ReadFileToBuffer(...) will fail if the maximum allowed size is less than
the value returned by GetPageSizeCached()). For example, on my PPC64/Linux
system, GetPageSizeCached() returns 2^16. In case the page size is larger, use
that instead.

builtins: avoid duplicating unwind declarations

Use unwind.h to get the declarations for unwinding interfaces. This header is

building the builtins library. It avoids the duplication which may drift over

Summary:
On Linux in some situations we can get SIGBUS instead of SIGSEGV on
stack overflow, so asan should handle SIGBUS as well as SIGSEGV.

Summary:
Introduce a single place where we specify flag type, name, default

Revert "Revert r224736: "[Sanitizer] Make CommonFlags immutable after initialization.""
...
Fix test failures by introducing CommonFlags::CopyFrom() to make sure
compiler doesn't insert memcpy() calls into runtime code.
Original commit message:
Protect CommonFlags singleton by adding const qualifier to
common_flags() accessor. The only ways to modify the flags are
SetCommonFlagsDefaults(), ParseCommonFlagsFromString() and
OverrideCommonFlags() functions, which are only supposed to be
called during initialization.

We've got some internal users that either aren't compatible with this or
have found a bug with it. Either way, this is an isolated cleanup and so
I'm reverting it to un-block folks while we investigate. Alexey and
I will be working on fixing everything up so this can be re-committed
soon. Sorry for the noise and any inconvenience.
