Libraries update and some chores

[mmicko]

• Update GLM to 1.0.3
• Update pugixml to v1.16
• cleanup: remove execute flag from files
• cleanup: remove BOM
• Updated utf8proc to v2.11.3
• frontend: fixed exit with "-ui simple"

[mmicko]

It is large number or files, but GLM have quite big number of documentation files that makes this PR much bigger than it should be.
Impact is not that big, glm is used currently by one driver only, and pugixml is for softlists for now.

63a8a30 takes care of a few of these:

• INI files with stray U+FEFF (and adds a makefile rule to take care of these)
• Stray execute bits.
• Some isues handling “main menu” mode in selmenu.cpp and simpleselgame.cpp (although there are still some issues with handling the situation where UI Back and UI Cancel have different across the menus).

The Visual Studio project files in the netlist project shoudn’t have the U+FEFF stripped as Visual Studio always re-adds it to project files.

Thanks. Should I rebase and leave just lib changes, or you are cherry picking/updating libs ?

[cuavas]

Just leave it, no need to rebase. I’ll cherry-pick and/or adjust them as I go.

uttf8proc (94c6e34) and zstd (f9050e8) are done.

[cuavas]

GLM is done in bb6e4fd (and LZMA was done in c23567b).

[cuavas]

ASIO is done in 89e00b9, and code now builds with all currently deprecated ASIO features disabled.

pugixml updated in 9d9e0fd (it’s only used for HSI files, software lists use expat SAX parser).
