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().

7b0eeda1c6 Remove aes256estream. 
AES-256 will be reintroduced, but not until we have a bitsliced implementation.

a7410966ea Rename secretbox_chacha20poly1305() -> aead_chacha20poly1305() 
The tag is still at the end. This will be changed right after.

bd1490a6cd Add AEAD_CHACHA20_POLY1305 
With a twist: in order to be consistent with the crypto_stream
interface, the tag has to come before the ciphertext.

Go back to masking the high bit in curve25519 instead of processing the
key as a 256-bit value.

e1218882d4 Initial commit for contribution of documentation. 
+ Updated `.gitignore`
+ Added `Doxyfile`.

[Doxygen](http://www.doxygen.org) has been setup to look for documented `C` fles within:

+ `src/sodium/includes`; and
+ `test`

When run with the Doxygen tool documentation will be generated within
the directory `doxydoc`. The projects README.markdown file is used at
the documentation's main page.

More information on Doxygen tags and abilities can be found on the
projects website: http://www.doxygen.org

test/default contains only tests using the default primitives
for a given operation. We need to add other tests as well.
