Writes out symbol values as a C header file.
Based on Kconfig's write_autoconf function.
The ordering of the #defines matches the one generated by
write_config(). The order in the C implementation depends on the hash
table implementation as of writing, and so won't match.
filename:
Self-explanatory.
header (default: "/* Generated by Kconfiglib (https://github.com/ulfalizer/Kconfiglib) */\n"):
Text that will be inserted verbatim at the beginning of the file. You
would usually want it enclosed in '/* */' to make it a C comment,
and include a final terminating newline.
