Only for SunCC for now.

It turns out that some compilers to generate external variants of
unused static inline functions, and if they use other external
symbols, those need to be present as well.  If you then happen to
include one of safestack.h or lhash.h without linking with libcrypto,
the build fails.

This is a combination of sk_new and sk_reserve, to make it more
convenient to allocate a new stack with reserved memory and comaprison
function (if any).

This allows the caller to guarantee that there is sufficient space for a
number of insertions without reallocation.

The expansion ratio when reallocating the array is reduced to 1.5 rather than 2.

Change bounds testing to use a single size rather than both INT_MAX and
SIZE_MAX.  This simplifies some of the tests.

Switch the stack pointers to data from char * to void *

It is expensive to create the ASYNC_JOB objects due to the "makecontext"

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.
