Log message:
Teach bsd.pkg.mk to create a phase-specific "makevars.mk" file that
caches variable definitions that were computed by make.  These variables
are specified by listing them in MAKE_VARS, e.g.,

	.if !defined(FOO)
	FOO!=	very_time_consuming_command
	.endif
	MAKE_VARS+=	FOO

bsd.pkg.mk will include only the one generated during the most recent
phase.  A particular phase's makevars.mk file consists of variable
definitions that are a superset of all of the ones produced in previous
phases of the build.

The caching is useful because bsd.pkg.mk invokes make recursively,
which in the example above has the potential to run the very time-consuming
command each time unless we cause FOO to be defined for the sub-make
processes.  We don't cache via MAKE_FLAGS because MAKE_FLAGS isn't
consistently applied to every invocation of make, and also because
MAKE_FLAGS can overflow the maximum length of a make variable very
quickly if we add many values to it.

One important and desirable property of variables cached via MAKE_VARS
is that they only apply to the current package, and not to any
dependencies whose builds may have been triggered by the current
package.

The makevars.mk files are generated by new targets fetch-vars,
extract-vars, patch-vars, etc., and these targets are built during
the corresponding real-* target to ensure that they are being invoked
with PKG_PHASE set to the proper value.

Also, remove the variables cache file that bsd.wrapper.mk was generating
since the new makevars.mk files provide the same functionality at a
higher level.  Change all WRAPPER_VARS definitions that were used by
the old wrapper-phase cache file into MAKE_VARS definitions.

Log message:
PKG_OPTIONS.<pkg> isn't a good approximation to PKG_OPTIONS for the
package because PKG_OPTION.<pkg> could contain negative options, which
are never part of PKG_OPTIONS.  Instead, use the show-var target to
display the value.  We cache it in WRAPPER_VARS and in MAKE_FLAGS to
prevent reinvoking the show-var target recursively.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Update security/openssl to openssl-0.9.7f.

Pkgsrc changes from version 0.9.7e include:

  *) Install the man pages with names that are less likely to collide
     with other packages' man pages.
  *) Support PKG_OPTIONS of "idea", "mdc2" and \ 
"rc5" to allow building
     with patented algorithms.  By default, this package still builds
     without patented algorithms.

Major changes from version 0.9.7e include:

  *) Prompt for pass phrases when appropriate for PKCS12 input format.
  *) Back-port of selected performance improvements from development
     branch, as well as improved support for PowerPC platforms.
  *) Add lots of checks for memory allocation failure, error codes to indicate
     failure and freeing up memory if a failure occurs.
  *) Add new -passin argument to dgst.
  *) Make an explicit check during certificate validation to see that
     the CA setting in each certificate on the chain is correct.

Log message:
Add RMD160 digests.

Log message:
when linking shared libssl on Solaris, make sure the rpath is
included so it can find libcrypto.

Log message:
Modify openssl/Makefile so that it's easier to test the -STABLE and
-SNAP OpenSSL snapshots.

Log message:
when building with SunPro on x86, do not use -fast argument to cc(1)
because:

- its behaviour changes between releases
- it uses build-host specific instructions where possible,
  specifically on >= Solaris 9 update 6 and Sun Studio 9 (sse, sse2)

this breaks using the binary pkg when installed on systems with a
less capable processor. instead, just use -xO5 so the binary pkg will
work everywhere.

Log message:
Bump PKGREVISION to 1 as a result of fixing the run-time behavior of
openssl on sparc64 and amd64 in the previous commit.

Log message:
Optimize the NetBSD/amd64 config a bit to improve RC4 performance, and
fix the NetBSD/sparc64 config by adding -DMD32_REG_T=int to the flags.
Tested by martin (at) NetBSD.org.  This should fix PR pkg/28858.
