all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
lang: align variable assignments

pkglint -Wall -F --only aligned --only indent -r

No manual corrections.

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
Do not build with the gcc-java enabled by default.

Log message:
Attempt to bring sanity to how ABI and MACHINE_ARCH are set.

Previously there were at least 5 different ways MACHINE_ARCH could be set,
some statically and some at run time, and in many cases these settings
differed, leading to issues at pkg_add time where there was conflict
between the setting encoded into the package and that used by pkg_install.

Instead, move to a single source of truth where the correct value based on
the host and the chosen (or default) ABI is determined in the bootstrap
script.  The value can still be overridden in mk.conf if necessary, e.g.
for cross-compiling.

ABI is now set by default and if unset a default is calculated based on
MACHINE_ARCH.  This fixes some OS, e.g. Linux, where the wrong default was
previously chosen.

As a result of the refactoring there is no need for LOWER_ARCH, with
references to it replaced by MACHINE_ARCH.  SPARC_TARGET_ARCH is also
removed.

Log message:
Remove mk/find-prefix.mk usage from the lang category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
