databases/py-lmdb: Fix build after lmdb update.

Approved by:	bapt

databases/lmdb: allow to install both 0.x and 1.x together

LMDB 1.0 and the legacy 0.9 ABI cannot be mixed, the datanase format are
incompatibles as well.

Rename or relocate everything databases/lmdb0 installs so that it no
longer overlaps with databases/lmdb:
- the utilities are now mdb_copy0, mdb_dump0, mdb_load0 and mdb_stat0
- the header is include/lmdb0/lmdb.h
- the linker name is liblmdb0.so, the shared object keeps its ABI name
  liblmdb.so.0 so already linked programs are unaffected
- the pkg-config file is lmdb0.pc

A compatibility prefix holding the previous layout is also installed
under ${PREFIX}/lmdb0/ (include/, lib/ and libdata/pkgconfig/) so that
build systems which expect to find lmdb.h and -llmdb relative to a
single directory only need a path change.

Now all ports should migrate to lmdb 1.X and use the lmdb 0.9 port to ease
in the migration path, lmdb, the lmdb 0.x is supposed to get removed at
some point.

databases/lmdb0: Add port for LMDB 0.9.x legacy ABI

LMDB 1.0 introduced an incompatible on-disk format change and subtle
API breakage: applications that compiled cleanly against 1.0 headers
could fail silently at run time. Known affected ports include dns/knot3,
mail/bogofilter, and mail/postfix; the postfix issue has been confirmed
upstream. Linux distributions such as Arch Linux have observed the same
breakage. Samba can also be affected in certain configurations.

Because the regression is not detectable in an -exp build run -- the
postfix failure only manifests at run time, and bogofilter was caught
only because post-build self-tests happen to exercise this path -- we
cannot rely on package builds to validate the 1.0 upgrade.

This commit introduces databases/lmdb0 as a holding port for the 0.9.35
release, pinned to the 0.x branch with PORTSCOUT=limit:^0. and mutually
conflicting with databases/lmdb, which retains 1.0. The two packages
cannot be installed simultaneously, but having lmdb0 available means:

* Ports known to require the 0.9 ABI can declare an explicit dependency
  on databases/lmdb0 until they are validated against 1.0.
* Users with existing databases in the 0.9 format can still access the
  mdb_dump and mdb_load utilities to migrate data before upgrading.
* The package conflict prevents accidental mixing.

All 50 direct dependents of databases/lmdb are redirected to
databases/lmdb0 for now with a PORTREVISION bump, effectively restoring
the tree to the state prior to the LMDB 1.0 update. Once all dependent
ports are validated against LMDB 1.0, they will be moved back to
databases/lmdb and databases/lmdb0 will be removed.

python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.

all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Remove # $FreeBSD$ from Makefiles.

Drop python 2.7 support from a few ports

With hat:	portmgr

Relax hardcoded paths to fix build with Python 3.8.7

Since r558913 Python 3.8 incorporates BPO-42604 [1] which changed the
shared libs naming scheme.  This means "EXT_SUFFIX" is now derived from
SOABI and yields with Python 3.8 to ".cpython-38.so" instead of ".so".

The affected ports strip the libaries in the "post-install" target via
hardcoded path(s) and the build fails at the end because the new extension
is not expected at this place.

Remedy the issue by adding wildcards to these paths.  This should also
prepare the ports for future Python releases, which will use the new shared
libs naming scheme.

databases/py-lmdb: Update to 0.97

* Update WWW field as upstream has a new maintainer.

* While I'm here: Add "do-test" target to make future QA easier.

Notable changes since 0.93:

* Only preload the value with the GIL (= Global Interpreter Lock) unlocked
  when the value is actually requested. This significantly improves read
  performance to retrieve keys with large values when the value isn't
  retrieved.

* Handling of the Environment(create=True) flag was improved.

* Database names may be reused after they are dropped on CFFI, without
  reopening the environment.

* Python argument parsing now matches the behaviour of CFFI, and most sane
  Python APIs: a bool parameter is considered to be true if it is any truthy
  value, not just if it is exactly True.

* Updated LMDB to version 0.9.22.

* Fixed several 2.7/3 bugs in command line tool.

Use PY_FLAVOR for dependencies.

FLAVOR is the current port's flavor, it should not be used outside of
this scope.

Sponsored by:	Absolight

Convert Python ports to FLAVORS.

Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the
  current python flavor.  It can be used in dependency lines when the
  port itself is not python flavored.  For example, deskutils/calibre.

  By default, all the flavors are generated.  To only generate flavors
  for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
  BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.

  In all the ports with Python dependencies, the *_DEPENDS entries MUST
  end with the flavor so that the framework knows which to build/use.
  This is done by appending '@${PY_FLAVOR}' after the origin (or
  @${FLAVOR} if in a Python module with Python flavors, as the content
  will be the same).  For example:

    RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}
