Add a dozen more const declarations where appropriate.
These are from Justin; while adding his patch, I noticed
ASN1_BIT_STRING_check could be fixed, too.

Undo unapproved commit that removed DJGPP and WATT32

DJGPP is no longer a supported platform.  Remove all #ifdef, etc.,
cases that refer to it.  DJGPP also #define'd WATT32, so that
is now removed as well.

The call to setenv in gost2814789t.c is not portable and may
not reflect the location of the GOST ENGINE on all platforms anyway.
Instead set OPENSSL_ENGINES in test/Makefile

Original definition depended on __LONG_MAX__ that is not guaranteed to
be present. As we don't support platforms with int narrower that 32 bits
it's appropriate to make defition inconditional.

Correctly handle local machine keys in the capi ENGINE.

Multiple copies of the ENGINE will cause problems when it is cleaned up as
the methods are stored in static structures which will be overwritten and
freed up more than once.

Set static methods to NULL when the ENGINE is freed so it can be reloaded.
