[PATCH v2 0/5] mmc-utils: improve lsmmc usability

[Torstein Eide <torsteine@gmail.com>]

This series improves lsmmc in four areas: external manufacturer ID files,
accepting /dev and /sys/block paths for register reads, an mmc list command,
and bash completion for mmc-utils.

A cleanup patch is prepended to refactor CID parsing into shared structs and
helpers used by all three print functions.

Changes since v1 (review by Avri Altman):
- Patch 1 (new): refactor CID parsing into struct sd_cid/mmc_cid and
  parse_sd_cid()/parse_mmc_cid() helpers; used by print_sd_cid,
  print_mmc_cid, and print_list_entry
- Patch 2: get_manufacturer: fix static buffer lifetime, return strdup()
- Patch 2: get_manufacturer: simplify fopen fallback, warn once if ids
  files missing
- Patch 2: replace read_file() with read_file_at(dir, name), remove all
  chdir() calls
- Patch 2: struct config: remove ids_dir field
- Patch 2: print_sd_cid, print_mmc_cid: free() the manufacturer string
- Patch 3: resolve_dev_path: use stack buffer, strip partition suffix,
  validate device type
- Patch 4: month_name: switch to 0-indexed 16-entry array, drop "???" sentinel
- Patch 4: do_list: move struct config outside loop
- Patch 4: do_list: remove redundant access() check
- Patch 5: bash completion: accept more than 9 devices (/dev/mmcblk[0-9]
  replaced with compgen -G + grep regex)
