Check for missing engine name, and also, do not count up the number of given algorithms when an engine is given

p_CSwift_AttachKeyParam actually returns more than one kind of error.  Detect the input size error, treat any that are not specially checked as 'request failed', not as 'provide parameters', and for those, add the actual status code to the error message

Cryptoswitch actually has a few more statuses than SW_OK.  Let's provide the possibility for a better granularity in error checking

the configuration parameter 'no-hw'.

OpenSSL to have to opt out hardware support instead of having to opt
it in.  And since the hardware support modules are self-contained and
actually check that the vendor stuff is loadable, it still works as
expected, or at least, so I think...

it functional :-).

logstream.

Rename 'hwcrhk' to 'ncipher' in all public symbols.  Redo the logging function so it takes a BIO.  Make module-local functions static

the one line turns an error return value into a success return value.
:-) "openssl speed -engine hwcrhk rsa1024" now passes through ok.

correct the DSO-dependant code in the engine code.

now less so.

    Atalla code to see if the accelerator is running.
(2) Turn some spaces into tabs.

It's cute to observe that Atalla having no RSA-specific form of mod_exp
causes a DSA server to achieve about 6 times as many signatures per
second than an RSA server. :-)

Atalla card, you should be able to compile with the "hw-atalla" switch
with "./config" or "perl Configure", and then you can use the command-
line switch "-engine atalla" inside speed, s_cient and s_server (after
checking out note (1)).

Notes:
  (1) I've turned on native name translation when loading the shared-
      library, but this means that the Unix shared library needs to be
      libatasi.so rather than atasi.so. I got around this in my testing
      by creating a symbollic link from /usr/lib/libatasi.so to the real
      library, but something better will be needed. It also assumes in
      win32 that the DLL will be called atasi.dll - but as I don't have
      a win32/atalla environment to try I have no idea yet if this is
      the case.
  (2) Currently DSA verifies are not accelerated because I haven't yet
      got a mod_exp-based variant of BN_mod_exp2_mont() that yields
      correct results.
  (3) Currently the "init()" doesn't fail if the shared library can
      load successfully but the card is not operational. In this case,
      the ENGINE_init() call will succeed, but all RSA, DSA, DH, and
      the two BN_*** operations will fail until the ENGINE is switched
      back to something that does work. I expect to correct this next.
  (4) Although the API for the Atalla card just has the one crypto
      function suggesting an RSA private key operation - this is in
      fact just a straight mod_exp function that ignores all the RSA
      key parameters except the (private) exponent and modulus. This is
      why the only accelerator work is taking place inside the mod_exp
      function and there's no optimisation of RSA private key operations
      based on CRT etc.

wrong.  Additionally, just give a new value to hndidx once.

whatever the underlying API is. It must return (void *) because shared
libraries can expose functions, structures, or whatever. However, some
compilers give loads of warnings about casted function pointers through
this code, so I am explicitly casting them to the right prototypes.

(initiated by ./config and the presence of SDK headers) are conflicting.

should be NULL'd out.

engine list if HW_NCIPHER is defined. I want to play :-)

- implemented nCipher support via the nfhwcrhk library (not well tested).
- make update + make depend

  OPENSSL_malloc and OPENSSL_free.

* 3 "normal" files (crypto/rsa/rsa_lib.c, crypto/dsa/dsa_lib.c
  and crypto/dh/dh_lib.c) had their Malloc's and Free's missed
  when Richard merged the changes across to this branch -
  probably because those files have been changed in this branch
  and gave some grief to the merge - so I've changed them
  manually here.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.
