[Emc-developers] [PATCH 1/3] halui: Added awk script to generate size list

[Pavel S. <sh...@me...>]

Script takes halui_str structure and parses types from it.
For every variable it creates list entry with its size.
For array variables list of sizes is added.

Makefile rule is added to generate halui_size.h
