CA setting in each certificate on the chain is correct. As a side-
effect always do the following basic checks on extensions, not just
when there's an associated purpose to the check:
- if there is an unhandled critical extension (unless the user has
chosen to ignore this fault)

Define my own macro LP_ENTRY_SIZE to express the size of my own
buffering of directory entries, and make it depend on whichever comes
first of PATH_MAX and NAME_MAX. As a fallback, make sure it's set to
255 if neither PATH_MAX or NAME_MAX were defined. Also, if the size
given from PATH_MAX or NAME_MAX is less than 255, force LP_ENTRY_SIZE
to be 255.
It makes no harm whatsoever if LP_ENTRY_SIZE is larger than the
maximum local path name limit. It does make a lot of harm if
LP_ENTRY_SIZE is smaller. 255 seemed like a fairly acceptable default
when nothing else is available.

NB: I've removed the "BN_clear_free()" loops for the exit-paths in some of
these functions, and that may be a major part of the performance
improvements we're seeing. The "free" part can be removed because we're
using BN_CTX. The "clear" part OTOH can be removed because BN_CTX
destruction automatically performs this task, so performing it inside
functions that may be called repeatedly is wasteful. This is currently safe
within openssl due to the fact that BN_CTX objects are never created for
longer than a single high-level operation. However, that is only because
there's currently no mechanism in openssl for thread-local storage. Beyond
that, this might be an issue for applications using the bignum API directly
and caching their own BN_CTX objects. The solution is to introduce a flag
to BN_CTX_start() that allows its variables to be automatically sanitised
on release during BN_CTX_end(). This way any higher-level function (and
perhaps the application) can specify this flag in its own
BN_CTX_start()/BN_CTX_end() pair, and this will cause inner-loop functions
specifying the flag to be ignored so that sanitisation is handled only once
back out at the higher level. I will be implementing this in the near
future.
little TODO list in there as well as the debugging code (only enabled if
BN_CTX_DEBUG is defined).
I'd appreciate as much review and testing as can be spared for this. I'll
commit some changes to other parts of the bignum code shortly to make
better use of this implementation (no more fixed size limitations). Note
also that under identical optimisations, I'm seeing a noticable speed
increase over openssl-0.9.7 - so any feedback to confirm/deny this on other
systems would also be most welcome.
operations no longer require two distinct BN_CTX structures. This may put
more "strain" on the current BN_CTX implementation (which has a fixed limit
to the number of variables it will hold), but so far this limit is not
triggered by any of the tests pass and I will be changing BN_CTX in the
near future to avoid this problem anyway.
This also changes the default RSA implementation code to use the BN_CTX in
favour of initialising some of its variables locally in each function.

data. The use of BN_set_word() to initialise a bignum to zero causes
needless allocation and gives it a return value that must be checked. This
change converts BN_zero() to a self-contained macro that has no
return/expression value and does not cause any expansion of bignum data.
Note, it would be tempting to rewrite the deprecated version as a
success-valued comma expression, such as;
#define BN_zero(a) ((a)->top = (a)->neg = 0, 1)
However, this evaluates 'a' twice and would confuse initialisation loops
(eg. while(..) { BN_zero(bn++) } ). As such, the deprecated version

VMS. The C RTL can handle it well if the "directory" is a logical
name with no colon, therefore ending being 'logname/file'. However,
if the given logical names actually has a colon, or if you use a full
VMS-syntax directory, you end up with 'logname:/file' or
'dev:[dir1.dir2]/file', and that isn't handled in any good way.
So, on VMS, we need to check if the directory string ends with a
separator (one of ':', ']' or '>' (< and > can be used instead [ and
])), and handle that by not inserting anything between the directory
spec and the file name. In all other cases, it's assumed the
directory spec is a logical name, so we need to place a colon between
it and the file.
