Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.

* Name: gets
|
|
*
|
|
* Description:
|
|
* gets() reads a line from stdin into the buffer pointed to by s until
|
|
* either a terminating newline or EOF, which it replaces with '\0'. Reads
|
|
* at most n-1 characters from stdin into the array pointed to by str until
|
|
* new-line character, end-of-file condition, or read error. The newline
|
|
* character, if encountered, is not saved in the arraay. A NUL character
|
|
* is written immediately after the last character read into the array, or
|
|
* to str[0] if no characters were read.
|
|
*
|
|
* If n is zero or is greater than RSIZE_MAX, a null character is written
|
|
* to str[0] but the function reads and discards characters from stdin
|
|
* until new-line character, end-of-file condition, or read error (not
|
|
* implemented).
|
|
*
|
|
* If n-1 characters have been read, continues reading and discarding the
|
|
* characters from stdin until new-line character, end-of-file condition,
|
|
* or read error.
