Log message:
pkglint: use Go module build, simplify Makefile

Add a go.mod file to the sources and pull in goyacc through a TOOL_DEPENDS.
Bump version to 22.2.7.

Log message:
Revbump all Go packages after go118 security update

Log message:
pkgtools/pkglint: update to 22.2.6

Changes since 22.2.5:

A makefile that adds a _VARGROUPS section is partly considered part of
the infrastructure. It may define and use variables from its own
namespace. For example, devel/cmake/build.mk adds _VARGROUPS+=cmake,
thereby reserving the namespace '_CMAKE_*' for itself.

Dependencies in BUILDLINK_API_DEPENDS and BUILDLINK_ABI_DEPENDS that
contain unresolved variable expressions are no longer marked as
redundant. They were marked as redundant before because '$', when
interpreted as a package version, was smaller than 0.0.

Log message:
pkgtools/pkglint: update to 22.2.5

Changes since 22.2.4:

Makefiles in wip/mk may use internal variables (starting with '_'), just
like their counterparts in main mk/.

Package versions containing letters are now parsed like in pkg_install.

Log message:
pkgtools/pkglint: update to 22.2.4

Changes since 22.2.3:

Manual pages must not be listed in the ALTERNATIVES file. Instead, they
are handled automatically based on the program in bin/ or sbin/.

Detect packages that use the tool pkg-config even though they don't need
it.

Log message:
pkgtools/pkglint: update to 22.2.3

Changes since 22.2.2:

CHECK_WRKREF is known to pkglint, which prevents conditions using this
variable from being simplified in a wrong way.

For variables that are guaranteed to be defined, suggest to simplify the
condition '!empty(VAR:M[Yy][Ee][Ss])' to '${VAR:M[Yy][Ee][Ss]}', as that
reduces the number of negations in the condition.

Detect redundant WRKSRC definitions and suggest to remove them.

Fix wrong "c99 is not valid for USE_LANGUAGES" warnings.

Log message:
pkgtools/pkglint: update to 22.2.2

Changes since 22.2.1:

Require the current checksum algorithms for pkgsrc-wip packages as well.
SHA1 and RMD160 are no longer allowed for distfiles.

Do not warn about 'Package should not' when checking .mk files in the
pkgsrc infrastructure.

Log message:
pkgtools/pkglint: update to 22.2.1

Changes since 22.2.0:

Suggest simpler condition when matching a variable against a pattern
(occurs 220 times in pkgsrc).

Improve explanation for documenting patches.
