473e1718cc Add sodium_{malloc,allocarray,free}() and sodium_mprotect_*() 
ptr = sodium_malloc(size) returns a pointer from which exactly "size" bytes
can be accessed.

ptr = sodium_allocarray(count, size) allocates enough storage space for
"count" pointers or scalars of unit size "size".

In both cases, the region is immediately followed by a guard page.
As a result, any attempt to access a memory location after ptr[size - 1] will
immediately trigger a segmentation fault.

The allocated region is mlock()ed and filled with 0xd0 bytes.

A read-only page with the size, a guard page, as well as a canary are
placed before the returned pointer.

The canary is checked by sodium_free(); as a result, altering data right
before ptr is likely to cause sodium_free() to kill the process.

sodium_free() munlock()s the region and fills it with zeros before
actually calling free().

sodium_mprotect_noaccess(), sodium_mprotect_readonly() and
sodium_mprotect_readwrite() can be used to change the protection on the set
of allocated pages.

Reverting the protection to read+write is not required before calling
sodium_free().
