Don't have #error statements in header files, but instead wrap
the contents of that file in #ifndef OPENSSL_NO_xxx
This means it is now always safe to include the header file.

1. Cleaned up eventfd handling
2. Reworked socket setup code to allow other algorithms to be added in
   future
3. Fixed compile errors for static build
4. Added error to error stack in all cases of ALG_PERR/ALG_ERR
5. Called afalg_aes_128_cbc() from bind() to avoid race conditions

This was done by the following

This engine is for developers of async aware applications. It simulates
asynchronous activity with external hardware. This initial version supports
SHA1 and RSA. Certain operations using those algorithms have async job
"pauses" in them - using the new libcrypto async capability.

Removed ability to set ex_data impl at runtime.  This removed these
three functions:
    const CRYPTO_EX_DATA_IMPL *CRYPTO_get_ex_data_implementation(void);
    int CRYPTO_set_ex_data_implementation(const CRYPTO_EX_DATA_IMPL *i);
    int CRYPTO_ex_data_new_class(void);
It is no longer possible to change the ex_data implementation at
runtime.  (Luckily those functions were never documented :)

Also removed the ability to add new exdata "classes."  We don't believe
this received much (if any) use, since you can't add it to OpenSSL objects,
and there are probably better (native) methods for developers to add
their own extensible data, if they really need that.

Replaced the internal hash table (of per-"class" stacks) with a simple
indexed array.  Reserved an index for "app" application.

Each API used to take the lock twice; now it only locks once.

Use local stack storage for function pointers, rather than malloc,
if possible (i.e., number of ex_data items is under a dozen).

Make CRYPTO_EX_DATA_FUNCS opaque/internal.

Also fixes RT3710; index zero is reserved.

Remove ERR_[gs]et_implementation as they were not undocumented and
useless (the data structure was opaque).

Halve the number of lock/unlock calls in almost all ERR_
functions by letting the caller of get_hash or int_thread_set
able to lock.  Very useful when looping, such as adding errors,
or when getting the hash and immediately doing a lookup on it.

Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.

Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.
