b39fc56061 Identify and move common internal libcrypto header files
There are header files in crypto/ that are used by a number of crypto/
submodules.  Move those to crypto/include/internal and adapt the
affected source code and Makefiles.

The header files that got moved are:

crypto/cryptolib.h
crypto/md32_common.h

4c9b0a0314 Initialize potentially uninitialized local variables
Compiling OpenSSL code with MSVC and /W4 results in a number of warnings.
One category of warnings is particularly interesting - C4701 (potentially
uninitialized local variable 'name' used). This warning pretty much means
that there's a code path which results in uninitialized variables being used
or returned. Depending on compiler, its options, OS, values in registers
and/or stack, the results can be nondeterministic. Cases like this are very
hard to debug so it's rational to fix these issues.

This patch contains a set of trivial fixes for all the C4701 warnings (just
initializing variables to 0 or NULL or appropriate error code) to make sure
that deterministic values will be returned from all the execution paths.

RT#3835

Signed-off-by: Matt Caswell <matt@openssl.org>

Matt's note: All of these appear to be bogus warnings, i.e. there isn't
actually a code path where an unitialised variable could be used - its just
that the compiler hasn't been able to figure that out from the logic. So
this commit is just about silencing spurious warnings.

2754597013 A general spring-cleaning (in autumn) to fix up signed/unsigned warnings.
I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.

1241126adf More linker bloat reorganisation:
Split private key PEM and normal PEM handling. Private key
handling needs to link in stuff like PKCS#8.

Relocate the ASN1 *_dup() functions, to the relevant ASN1
modules using new macro IMPLEMENT_ASN1_DUP_FUNCTION. Previously
these were all in crypto/x509/x_all.c along with every ASN1
BIO/fp function which linked in *every* ASN1 function if
a single dup was used.

Move the authority key id ASN1 structure to a separate file.
This is used in the X509 routines and its previous location
linked in all the v3 extension code.

Also move ASN1_tag2bit to avoid linking in a_bytes.c which
is now largely obsolete.

So far under Linux stripped binary with single PEM_read_X509
is now 238K compared to 380K before these changes.

Dr. Stephen Henson
19da130053 First of several reorganisations to
reduce linker bloat. For example the
single line:

PEM_read_X509()

results in a binary of around 400K in Linux!

This first step separates some of the PEM functions and
avoids linking in some PKCS#7 and PKCS#12 code.

cf1b7d9664 Make all configuration macros available for application by making
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

ecbe07817a Rewrite PKCS#12 code and remove some of the old
horrible macros.

Fix two evil ASN1 bugs. Attempt to use 'ctx' when
NULL if input is indefinite length constructed
in asn1_check_tlen() and invalid pointer to ASN1_TYPE
when reusing existing structure (this took *ages* to
find because the new PKCS#12 code triggered it).
