Picolibc version 1.7.7

1. Fix semihost gettimeofday, add a test.

2. Fix config option documentation. (Thanks to rdiez)

3. Document how re-entrant locking APIs are used. (Thanks to rdiez)

4. Fix some 16-bit int issues in tinystdio. (Thanks to Ayke van
   Laethem)

5. Make header files a bit more POSIX compliant, installing rpc
   headers, moving byte swapping macros to arpa/inet.h

6. Fix some stdio bugs found by Zephyr test suite: snprintf return
   value on buffer overflow, add ftello/fseeko, fputc return value,
   %0a formatting, clear EOF status after ungetc/fseek.

7. Re-do buffered I/O support to handle mixed read/write files
   correctly. This adds setbuf, setbuffer, setlinebuf, setvbuf.

8. Add fmemopen and freopen.

9. Add enough cmake support to allow Zephyr to build picolibc as a
   module using that, rather than meson.

10. Merge current newlib bits

11. Fix %p printf/scanf on ILP64 targets.
