Merge branch 'master' into lspci

Use Felix's version of lspci.
Add library code to look up descriptions.

Added to lib/ because it will be useful for both lspci and lsusb.
Hook up lspci text logic.

This involves:
-Build fix for id-db
-Add a counter for -n (for the sake of -nn)
-Add the stream "db" to GLOBALS and open it conditionally
-Add name fields to bufs
-Look up text if enabled and -n is passed never or twice
-Print text if lookup succeeded

-nn is not yet supported.
Shut up gcc. Yes, we want an assignment.
Support for -nn.
Reindent and move fseek.
Merge branch 'master' into xzcat
System V style init, submitted by Kyungwan Han.
Cleanup grep, make it pass the current test suite.
Fluff out grep test suite some more, including lots of things we don't pass yet.
I have implemented FDISK command.
This supports '-l' option for listing and other options [-bCHS] for giving
values like block size, Cylinders, Heads,...
This is the preliminary version of lspci text output support (the location
of pci.ids is hard-coded to /usr/share/misc/pci.ids, as found on Debian/Ubuntu).
+88 lines in two files, including reformatting, comments, whitespace,
and build configuration as well as new code.

The changes:
-Add library code to look up descriptions.
-Add a counter for -n (for the sake of -nn)
-Add the file stream "db" to GLOBALS and open it conditionally
-Add name fields to bufs
-Look up text if enabled and -n is passed never or twice
-Print text if lookup succeeded
Forgot to check in xfdopen(). My bad.

Failure of fdopen() is most likely failure of malloc() for the FILE structure.
Achille Fouilleul pointed out that fdlength wasn't returning the right length in the binary search case.

(This code was originally written for mke2fs, and applies to block devices. The regular file case should just return the length from stat. The ioctl is left commented out in case I want to add back code to check the size of CDROMs without spinning them up again; not sure the sector size is always right these days.)
Merge branch 'master' into lspci; lib/id-db.c is included in lspci
Merge branch 'lspci' into build after merging master.

import resolve_modalias.c to toys/pending/
New toy: fallocate
Use a string_list so we can lookup multiple aliases.
