bulk: Do not declare function prototypes using 'extern' keyword
By default, C function prototypes declared in headers are visible,
so there is no need to declare them as 'extern' functions.
Remove this redundancy in a single bulk commit; do not modify:
- meson.build (used to check function availability at runtime)
- pc-bios/
- libdecnumber/
- tests/
- *.c
