83b43443e5 threads: Automatically call ssh_init on load 
This makes unnecessary to call ssh_init() when the library is
dynamically loaded.  Also removes the threads shared library.  The used
threads implementation is chosen in configuration time, changing the
ssh_threads_get_default() depending on the available threads library.

Internally, it is expected a threads implementation providing:

- void ssh_mutex_lock(void **mutex);
- void ssh_mutex_unlock(void **mutex);
- struct ssh_threads_callbacks_struct *ssh_threads_get_default(void);

and a crypto implementation providing:

- int crypto_thread_init(struct ssh_threads_callbacks_struct *user_callbacks);
- void crypto_thread_finalize(void);

This adds internal threads implementation for pthreads and noop.

12284b75fa buffer: Add and use ssh_buffer_allocate_size() 
Add a small helper for ssh_buffer to ensure that the buffer has a
certain amount of space already preallocated. This can be useful in case
it is known how much data is going to be added to a buffer, to avoid
multiple reallocations.

Make use of it in few places in the library.

Thanks to Tilo Eckart.

The global variable "ge25519_base" is referenced in the module
"src/external/ed25519.c" and initialized in "src/external/ge25519.c".
The lack of the extern keyword in the header results in different
instances being compiled into both translation units with some
compilers.

be22c0d442 Add a NODELAY option 
Add a new option SSH_OPTIONS_NODELAY to enable or disable the
Nagle Algorithm (TCP_NODELAY) on the session socket.

Improved performance can be achieved for some applications like
sftp servers by enabling SSH_OPTIONS_NODELAY as typically, the
next request won't arrive until the server replies, which are
typically small writes.
