no longer violate the const part of 'const char *' in send functions.
FailMsg and LocMsg contain char* fields which are not const. Assigning
the passed const char* to a FailMsg or LocMsg violates the const.
To avoid this, a copy of the data is made using strdup. Yes, the
extra copy is functionally unnecessary, but to honor the const
it must be done.
The alternative is to make the char* fields in FailMsg and LocMsg
const. This will not work, however, as those fields are sometimes
assigned malloc'ed data in the code and free'd. You cannot pass
a const pointer to free without a warning.

Removing const identifier from List data structure
The const identifier on the data field of List would imply that
nothing is ever done to modify or destroy the data. However, the
data can be accessed later and modified or freed, as was being done
in places. By removing the const identifiers, the implied safety
of the stored values (which is being violated anyway) is not
advertised in the API.

change expected exit values of tests to consistently be signed chars
when a forked process finishes, waitpid() will return the status
as an int. Several macros determine what the status means.
WEXITSTATUS() is defined as returning the low-order 8 bits of the status
argument that the child process passed to _exit() or exit(), or the
value the child process returned from main(). It makes sense for the
value to be stored as either a signed or unsigned char. As the
decision is arbitrary (e.g. it only matters internally to check),
signed is used to keep consistent with the _tcase_add_test function.

libcompat: remove replacement for sleep()
Before working on MSVC support, the replacement sleep() call
