b03747e983 Reserve and ignore the a new module metadata type MDT_PNP_INFO for
associating an optional PNP hint table with this module. In the
future, when these are added, these changes will silently ignore the
new type they would otherwise warn about. It will always be safe to
ignore this data. Get this into the builds today for some future
proofing.

e808299c02 Bump the largest record we can cope with from 1k to 8k. Other users of
the hints file don't have any real limits, and longer records will
need to be written shortly.

5d452cea64 kldxref: Add static keyword to the new function only used in the same file.
The WARNS level is not such that the omission broke the build.

6d9cb20bd7 kldxref: Do not depend on the directory order.
Sort the filenames to get a consistent result between machines of the same
architecture.

Also, sort FTS_D entries after other entries so kldxref -R works properly in
the uncommon case that a directory contains both subdirectories and modules.
Previously, this may have happened to work, depending on the order of files
in the directory.

ddce581880 Make the linker.hints file have mode 644 instead of 600.
There is nothing secret in the file, and the missing read
permission breaks diskless operation.

2fdfd0fee2 Use safe strlcpy rather than unsafe strncpy. After marcel's last fix,
there was still one overflow possible.  strlcpy is faster anyway
because it doesn't unexpectedly zero the entire length of the string
when copying short strings....

77a6f8ac6f Fix (static) buffer overflow bug. The dest buffer is of size MAXPATHLEN,
so dest[MAXPATHLEN] falls outside the buffer.  This bug corrupted
arenas[0] defined in libc's malloc.c on PowerPC when kldxref is shared,
which triggered a delayed SIGSERV.

9ceddbd532 Change maketempfile() to return a FILE* so as to eliminate the fopen()
that immediately follows the only call to it. maketempfile() uses
mkstemp(), so the temporary file has already been opened and using
fopen() again just opens the file twice. This also fixes the invalid
mode used on the fopen().
While here, assign NULL to fxref after fclose() because we test for
fxref being !NULL to determine if we have the (temporary) hints file
open.

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.
