e961c7a201 Remove the "eay" c-file-style indicators
Since we don't use the eay style any more, there's no point tryint to
tell emacs to use it.

76067c75fd RT3757: base64 encoding bugs
Rewrite EVP_DecodeUpdate.

In particular: reject extra trailing padding, and padding in the middle
of the content. Don't limit line length. Add tests.

Previously, the behaviour was ill-defined, and depended on the position
of the padding within the input.

In addition, this appears to fix a possible two-byte oob read.

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.

60b7d3bbb5 Revert "RT3425: constant-time evp_enc"
Causes more problems than it fixes: even though error codes
are not part of the stable API, several users rely on the
specific error code, and the change breaks them. Conversely,
we don't have any concrete use-cases for constant-time behaviour here.

This reverts commit f2df488a1c.
