This patch exposes SharedMemoryBasic::Unmap for use by callers to allow
one to unmap memory out of our address space without destroying the
SharedMemoryBasic object itself. This will be used by later patches in
this series.

This patch adds two things:
1. An optional fixed_address argument to SharedMemoryBasic::Map, which
is the address to map the shared memory at.
2. A FindFreeAddressSpace function that callers can use to find a
contiguous block of free address space, which can then be used to
determine an address to pass in to Map that is likely to be free.
Patches in bug 1474793 will use these to place the User Agent style
sheets in a shared memory buffer in the parent process at an address
that is also likely to be free in content processes.
