This commit converts the license handling to adhere to the REUSE specification. It specifically: 1. Adds used licnses to LICENSES/ directory 2. Add "isc" template for adding the copyright boilerplate 3. Changes all source files to include copyright and SPDX license header, this includes all the C sources, documentation, zone files, configuration files. There are notes in the doc/dev/copyrights file on how to add correct headers to the new files. 4. Handle the rest that can't be modified via .reuse/dep5 file. The binary (or otherwise unmodifiable) files could have license places next to them in <foo>.license file, but this would lead to cluttered repository and most of the files handled in the .reuse/dep5 file are system test files.

|
# AX_RESTORE_FLAGS([namespace])
|
|
#
|
|
# DESCRIPTION

|
#

|
# Restore common compilation flags from temporary variables.

# Compilation flags includes: CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS, LIBS,
|
|
# OBJCFLAGS.

# AX_RESTORE_FLAGS(NAMESPACE) macro.
|
|
#
|
|
# Typical usage is like:
|
|
#
|
|
# AX_SAVE_FLAGS(mypackage)
|
|
# CPPFLAGS="-Imypackagespath ${CPPFLAGS}"
|
|
# dnl ... do some detection ...
