d8da8dcc44 libc: Print error code for unknown errors in strerror/gai_strerror
Ref: Linux print unknown errors like "Unknown error nnn"
https://man7.org/linux/man-pages/man3/strerror.3.html#RETURN_VALUE

Note:
These interfaces are called at low freq, so a static buffer may be enough.

185b1cb1b7 libc/string: strcmp/strncmp cast unsigned char
Summary:
- Cast to unsigned char for strcmp and strncmp
- strcmp and strncmp are described following by opengroup.org

  The sign of a non-zero return value shall be determined by the sign
  of the difference between the values of the first pair of bytes
  (both interpreted as type unsigned char) that differ in the strings
  being compared.

  https://pubs.opengroup.org/onlinepubs/9699919799/functions/strcmp.html
  https://pubs.opengroup.org/onlinepubs/9699919799/functions/strncmp.html

Impact:
- strcmp and strncmp return value

Testing:
- ostest on sabre-6quad:smp w/ qemu
