Fix corner case uses of memory_buffer_alloc.c

Browse source 
The corner cases fixed include:
    * Allocating a buffer of size 0. With this change, the allocator now
      returns a NULL pointer in this case. Note that changes in pem.c and
      x509_crl.c were required to fix tests that did not work under this
      assumption.
    * Initialising the allocator with less memory than required for headers.
    * Fix header chain checks for uninitialised allocator.
