/* The functions declared here are used when passing inferior arguments
from GDB to gdbserver.
The remote protocol requires that arguments are passed as a vector of
separate argument while GDB stores the arguments as a single string, and
gdbserver also requires the arguments be a single string.
These functions then provide a mechanism to split up an argument string
and recombine it within gdbserver while preserving escaping of special
characters within the argument string. */

inferior argument string. The string returned by this function will be
equivalent, but not necessarily identical to the string passed to
::split, for example passing the string '"a b"' (without the single
quotes, but including the double quotes) to ::split, will return an
argument of 'a b' (without the single quotes). When this argument is
passed through ::join we will get back the string 'a\ b' (without the
single quotes), that is, we choose to escape the white space, rather
than wrap the argument in quotes. */
