6188667476 Revert the change to make the pool global type safe. 
This adds lazy initialization, which adds a conditional branch on some
hot paths.

Fixes #93

9eaadcd6d8 Reduce parallism in tests 
If some tests on Windows are co-scheduled, then they run out of commit
space and crash. For example, in func-memory,
test_external_pointer_large can cause the small CI machines to run out
of commit space on Windows.

6dbe24da2e [NFC] Replace HEADER_GLOBAL with inline (C++17). 
HEADER_GLOBAL was using non-standard attributes to achieve what C++17
now permits with a keyword.  Use the standard formulation.

Update the README to note that gcc is still not recommended, but because
of its poor codegen for 128-bit atomic compare and exchange, rather than
because it doesn't support the attribute used for HEADER_GLOBAL.

d2dc653af2 Make the pagemap global typed. 
The pagemap global is now an inline static of a template class, so that
we will see different symbols for the different types.

Issue #84 showed that it's possible to compile two compilation units
with different pagemaps, link them together, and have them attempt to
interpret the global pagemap as two different types.  This change should
make that impossible.

Also make the `pagemap()` function static so that it can be used from
static functions, avoiding other things that directly reference the
global pagemap.

2b44b6b5ea Add a NetBSD PAL. 
Currently untested, but identical to the FreeBSD one so should work...
The NetBSD man pages for `madvise` and `mmap` mention the flags that we
use.

4ed15def79 [NFC] Remove some code duplication in the PALs. 
Pull out a generic POSIX PAL as a superclass for the Linux and generic
BSD PALs.  Now we have FreeBSD and Linux adding OS-specific behaviour,
OpenBSD as a named subclass of the generic BSD PAL that doesn't add any
behaviour.

I believe a NetBSD PAL should now be identical to the OpenBSD one -
patches welcome if anyone wants to test one!

b2b86565db Use get_noncachable in malloc/new overrides. 
This may return the GlobalPlaceholder, in which case the slow path will
be used, initializing the real thread local allocator.
