Philippe Mathieu-Daudé f703f1ef99 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
