@brief Prohibits access to unused memory pages in Botan's memory pool
If BOTAN_MEM_POOL_USE_MMU_PROTECTIONS is defined, the Memory_Pool
class used for mlock'ed memory will use OS calls to set page
permissions so as to prohibit access to pages on the free list, then
enable read/write access when the page is set to be used. This will
turn (some) use after free bugs into a crash.
The additional syscalls have a substantial performance impact, which
is why this option is not enabled by default. It is used when built for
running in valgrind or debug assertions are enabled.

Initialize a memory pool. The memory is not owned by *this,
it must be freed by the caller.
@param pages a list of pages to allocate from
@param page_size the system page size, each page should
point to exactly this much memory.
