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().

c7059e88ec Always install the .pc file even if pkg-config is not available. 
And make sure that "make uninstall" gets rid of it, too.

098bad385b Disable memset_s test for now. 
Targeting OSX < 10.9 with -macosx-version-min doesn't work as expected:
memset_s is detected as present even though it won't actually work on
OSX <= 10.8

d889492173 Add ./configure option to disable toggle versions 
I consider this way cleaner than setting some environment
variable in the build script. Per default, sonames are generated.
If ./configure is run with "--disable-soname-versions", no soname
versions will be generated. This is mainly useful for android, but
it might find some use for other environments without soname versioning
