df57947f08 spdx: initial adoption of licensing ID tags.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

b6c03f2122 kldxref: bump MAXSEGS to 3
ld.bfd generates two PT_LOAD segments, but certain linkers or linker
configurations generate three PT_LOAD segments (one additional for
RELRO).

2bd7b9e5cc kldxref: Clean up error reporting
Omit "too many sections" warnings if the ELF file is not dynamically
linked (and is therefore skipped anyway), and otherwise output it only
once.  An errant core file would previously cause kldxref to output a
number of warnings.

Also introduce a MAXSEGS #define and replace literal 2 with it, to make
comparisons clear.

757686b115 Make our ELF64 type definitions match standards. In particular this
means:
o  Remove Elf64_Quarter,
o  Redefine Elf64_Half to be 16-bit,
o  Redefine Elf64_Word to be 32-bit,
o  Add Elf64_Xword and Elf64_Sxword for 64-bit entities,
o  Use Elf_Size in MI code to abstract the difference between
   Elf32_Word and Elf64_Word.
o  Add Elf_Ssize as the signed counterpart of Elf_Size.

9dba198b0e Explicitly pass in the relocation base and data offset into ef_reloc()
rather than relying on a trick that happens to work for the current
relocation schemes. Also add some comments and improve variable
naming.

9772dc2aff Call the file format specific code through a table of function
pointers and remove knowledge of the file format from kldxref.c.
This will make it possible to support more than one file format.

1eed250ad8 Fix kldxref on sparc64 by allowing non-trivial relocations to be performed
on variables read out of raw kld files.  Unlike other platforms the value
will be in an Elf_Rela, not in the data section of the elf file.

module->pathname.ko.  It supports only ELF for now.
