eb797fde3f Fix the update target and remove duplicate file updates
We had updates of certain header files in both Makefile.org and the
Makefile in the directory the header file lived in.  This is error
prone and also sometimes generates slightly different results (usually
just a comment that differs) depending on which way the update was
done.

This removes the file update targets from the top level Makefile, adds
an update: target in all Makefiles and has it depend on the depend: or
local_depend: targets, whichever is appropriate, so we don't get a
double run through the whole file tree.

bd41063b11 Don't set *pval to NULL in ASN1_item_ex_new.
While *pval is usually a pointer in rare circumstances it can be a long
value. One some platforms (e.g. WIN64) where
sizeof(long) < sizeof(ASN1_VALUE *) this will write past the field.

*pval is initialised correctly in the rest of ASN1_item_ex_new so setting it
to NULL is unecessary anyway.

Thanks to Julien Kauffmann for reporting this issue.

e6dcb08984 ASN1_primitive_new NULL param handling
ASN1_primitive_new takes an ASN1_ITEM * param |it|. There are a couple
of conditional code paths that check whether |it| is NULL or not - but
later |it| is deref'd unconditionally. If |it| was ever really NULL then
this would seg fault. In practice ASN1_primitive_new is marked as an
internal function in the public header file. The only places it is ever
used internally always pass a non NULL parameter for |it|. Therefore, change
the code to sanity check that |it| is not NULL, and remove the conditional
checking.

a8565530e2 Fix various certificate fingerprint issues.
By using non-DER or invalid encodings outside the signed portion of a
certificate the fingerprint can be changed without breaking the signature.
Although no details of the signed portion of the certificate can be changed
this can cause problems with some applications: e.g. those using the
certificate fingerprint for blacklists.

1. Reject signatures with non zero unused bits.

If the BIT STRING containing the signature has non zero unused bits reject
the signature. All current signature algorithms require zero unused bits.

2. Check certificate algorithm consistency.

Check the AlgorithmIdentifier inside TBS matches the one in the
certificate signature. NB: this will result in signature failure
errors for some broken certificates.

3. Check DSA/ECDSA signatures use DER.

Reencode DSA/ECDSA signatures and compare with the original received
signature. Return an error if there is a mismatch.

This will reject various cases including garbage after signature
(thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
(negative or with leading zeroes).
