This changes the condition to use the static error check mutex
initializer. If it is not available, use the default static mutex
initializer.

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.

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.

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.

The stray semi-colon in sftp.h is flagged when using -pedantic
which affects clients that include the header and use -pedantic
and -Werror on their codebase.
