- Replace external -DOPENSSL/-DPKCS11CRYPTO with properly AC_DEFINEd
  HAVE_OPENSSL/HAVE_PKCS11
- Don't enforce the crypto provider from platform.h, just from dst_api.c
  and configure scripts

The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.

The isc_random family of functions internally use these CSPRNG (if available):

1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library

libdns refactoring: get rid of multiple versions of dns_xfrin_create, dst_key_generate, dst_lib_init and dst_context_create

3786.	[func]		Provide more detailed error codes when using
			native PKCS#11. "pkcs11-tokens" now fails robustly
			rather than asserting when run against an HSM with
			an incomplete PCKS#11 API implementation. [RT #35479]

3705.	[func]		"configure --enable-native-pkcs11" enables BIND
			to use the PKCS#11 API for all cryptographic
			functions, so that it can drive a hardware service
			module directly without the need to use a modified
			OpenSSL as intermediary (so long as the HSM's vendor
			provides a complete-enough implementation of the
			PKCS#11 interface). This has been tested successfully
			with the Thales nShield HSM and with SoftHSMv2 from
			the OpenDNSSEC project. [RT #29031]

we no longer use basename() or dirname()

                        [RT #24711]

			to be fully automated in zones configured for
			dynamic DNS.  'auto-dnssec allow;' permits a zone
			to be signed by creating keys for it in the
			key-directory and using 'rndc sign <zone>'.
			'auto-dnssec maintain;' allows that too, plus it
			also keeps the zone's DNSSEC keys up to date
			according to their timing metadata. [RT #19943]

			private key file format, to allow implementation
			of explicit key rollover in a future release
			without impairing backward or forward compatibility.
			[RT #20310]

			Also, added warnings when revoking a ZSK, as this is
			not defined by protocol (but is legal).  [RT #19943]

- correctly use -K option in dnssec-keygen
- fix an improper free() in dnssec-revoke
- fix grammar in dnssec-settime

			- dnssec-keygen and dnssec-settime can now set key
			  metadata fields 0 (to unset a value, use "none")
			- dnssec-revoke sets the revocation date in
			  addition to the revoke bit
			- dnssec-settime can now print individual metadata
			  fields instead of always printing all of them,
			  and can print them in unix epoch time format for
			  use by scripts
			[RT #19942]

			key file paths correctly. [RT #20078]

			dnssec-* tools.  Major changes:
			- all dnssec-* tools now take a -K option to
			  specify a directory in which key files will be
			  stored
			- DNSSEC can now store metadata indicating when
			  they are scheduled to be published, acttivated,
			  revoked or removed; these values can be set by
			  dnssec-keygen or overwritten by the new
			  dnssec-settime command
			- dnssec-signzone -S (for "smart") option reads key
			  metadata and uses it to determine automatically
			  which keys to publish to the zone, use for
			  signing, revoke, or remove from the zone
