NCSI: Squash commits of NCSI and PCI-IDS

NCSI: Extends NCSI dissection based on DSP0222 Version: 1.2.0_2b

Add pci-ids.c and pci-ids.h for mapping PCI IDs(VID,DID,SID,SVID) to string.
Extends NCSI dissection to support DSP0222 Version: 1.2.0_2b.
Extends NCSI dissection to support Mellanox OEM commands.

NCSI: Use TFS for boolean mapped string and added AEN dissectors

1. Use the tfs defined in tfs.c
2. Refine the boolean mapped strings to be TFS style
3. Added dissectors for AEN

NSCI: Fixed erros with gcc 7.5.0

1. Fix compiling errors with gcc 7.5.0 under Ubuntu 18.04
2. Sloved complaints of git pre-commit hook

NCSI: Add "0x" prefix for displaying HEX values

There are codes display HEX values without prefix, added "0x" to fix that.

PCI-IDS: Added PCI ID file and python script to convert it to C codes

1. Added the PCI ID file pci.ids from https://pci-ids.ucw.cz/
2. Added pci-ids-convert.py to convert to epan/dissectors/pci-ids.c

PCI-IDS: Updated the PCI ID list to be Version 2021.01.11

NCSI: Remove trailing spaces and unused href entries

PCI-IDS: Use a fresh copy of pci.ids to generate pci-ids.c

1. Renamed pci-ids-convert.py to make-pci-ids.py
2. make-pci-ids.py uses a fresh copy of pic.ids to generate pci-ids.c

PCI-IDS: Move internal structure to C file

1. Move pci_id_t and pci_vid_index_t from header file to C file.
2. Refined the comments of pci-ids.c
3. Renamed local variable index (shadow variable) to idx

PCI-IDS: Refined binary search codes

PCI-IDS: Moved pci-ids.[ch] to epan/

Moved pci-ids.[ch] to epan/ as they ought to be
