Move the extern symbol declarations outside of

DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage.
Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

Make the JIT code emitter properly retry and ask for more memory when it runs

out of memory, and also make the default memory manager allocate more memory

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs. I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Eliminate the static constructors and locks from DynamicLibrary.cpp.
...
This fixes PR4512 and eliminating static ctors is always good. Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.
If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g. AddSymbol) in managed static objects.
Doing this would both fix memory leaks we already have, as well as make
the code thread safe again. it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into
System/Unix/DynamicLibrary.inc.

glibc has two versions of strerror_r, a standards compliant one and a GNU
...
specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.
This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.
