4a1f3f2741 Only declare stacks in headers 
Don't define stacks in C source files: it causes warnings
about unused functions in some compilers.

6756532358 Cleanup: Remove M_EVP_MD_* macros 
These macros were only meant for crypto/evp, and are now entirely
unused.

2db6bf6f85 Make the definition of EVP_MD opaque 
This moves the definition to crypto/include/internal/evp_int.h and
defines all the necessary method creators, destructors, writers and
accessors.  The name standard for the latter is inspired from the
corresponding functions to manipulate UI methods.

7638370ca6 Make the definition of EVP_MD_CTX opaque 
This moves the definitionto crypto/evp/evp_locl.h, along with a few
associated accessor macros.  A few accessor/writer functions added.

7a4bd34a4f FIPS mode EVP changes: 
Set EVP_CIPH_FLAG_FIPS on approved ciphers.

Support "default ASN1" flag which avoids need for ASN1 dependencies in FIPS
code.

Include some defines to redirect operations to a "tiny EVP" implementation
in some FIPS source files.

Change m_sha1.c to use EVP_PKEY_NULL_method: the EVP_MD sign/verify functions
are not used in OpenSSL 1.0 and later for SHA1 and SHA2 ciphers: the EVP_PKEY
API is used instead.

37c541faed Revert CFB block length change. Despite what SP800-38a says the input to 
CFB mode does *not* have to be a multiple of the block length and several
other specifications (e.g. PKCS#11) do not require this.

1458b931eb The "block length" for CFB mode was incorrectly coded as 1 all the time. It 
should be the number of feedback bits expressed in bytes. For CFB1 mode set
this to 1 by rounding up to the nearest multiple of 8.

b444ac3e6f size_t-fy EVP_CIPHER. Note that being size_t-fied it doesn't require 
underlying cipher to be size_t-fied, it allows for size_t, signed and
unsigned long. It maintains source and even binary compatibility.

b010b7c434 Use more flexible method of determining output length, by setting &outlen 
value of the passed output buffer is NULL.

The old method of using EVP_PKEY_size(pkey) isn't flexible enough to cover all
cases where the output length may depend on the operation or the parameters
associated with it.

a6cd870784 The AES modes OFB and CFB are defined with 128 feedback bits. This 
deviates from the "standard" 64 bits of feedback that all other
algorithms are using.  Therefore, let's redo certain EVP macros to
accept different amounts of feedback bits for these modes.

Also, change e_aes.c to provide all usually available modes for AES.
CTR isn't included yet.
