Traditionally Configure passed $ENV{PERL} to Makefile. But this
resulted in ambiguilty as Configure script could be executed by
interpreter different from one executing remaining scripts. Since
we separate compile- and run-time interpreters with HASHBANGPERL
variable, there is no reason to segment the build procedure.

A peer continually sending unrecognised warning alerts could mean that we
make no progress on a connection. We should abort rather than continuing if
we receive an unrecognised warning alert.

This is an internal API. Some of the tests were for programmer erorr and

A few style tweaks here and there. The main change is that curr and
packet_len are now offsets into the buffer to account for the fact that
the pointers can change if the buffer grows. Also dropped support for the
WPACKET_set_packet_len() function. I thought that was going to be needed
but so far it hasn't been. It doesn't really work any more due to the
offsets change.

The PACKET documentation is already in packet_locl.h so it makes sense to

The tests will only work in no-shared builds because WPACKET is an

The DSO API was picky about casing of symbol names on VMS.

There's really no reason to be that picky, it's mostly just annoying.
Therefore, we take away the possibility to flag for a choice, and will
instead first try to find a symbol with exact case, and failing that,
we try to find it in upper case.

This is generalised by having the following macros for stuff that won't
be installed:

    NO_INST_LIB_CFLAGS, used instead of LIB_CFLAGS
    NO_INST_DSO_CFLAGS, used instead of DSO_CFLAGS
    NO_INST_BIN_CFLAGS, used instead of BIN_CFLAGS

They take values from corresponding target config fields if those are
defined, otherwise they take the respective values from LIB_CFLAGS,
DSO_CFLAGS and BIN_CFLAGS.

Send a bit information to the build file template functions.  For
src2obj(), the additional option 'product' holds the name of the final
file that the object file will go into.  Additionally, the diverse
functions will get the option 'installed', with a value that evaluates
true if the final product is to be installed, otherwise false.

Certain functions are automatically called during auto-deinit in order
to deallocate resources. However, if we have never entered a function which
marks lib crypto as inited then they never get called. This can happen if
the user only ever makes use of a small sub-set of functions that don't hit
the auto-init code.

This commit ensures all such resources deallocated by these functions also
init libcrypto when they are initially allocated.

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath.  Unfortunately, this doesn't work
too well with asan, msan or ubsan.

So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.

This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.

Some hardware devices don't provide the public EC_POINT data. The only
way for X509_check_private_key() to validate that the key matches a
given certificate is to actually perform a sign operation and then
verify it using the public key in the certificate.

Maybe that can come later, as discussed in issue 1532. But for now let's
at least make it fail gracefully and not crash.
