Tests: test_downtime compiles again
Tests: test_nagios_config compiles and runs again.
Tests: Fix for test_commands resulting from previous update to stub_logging.c
xdata/status: Fix parameter passed to xsddefault_read_status_data()

Previously the name of the first parameter to xsddefault_read_status_data()
was cfgfile, but the value of the parameter was never used in the function.
Instead, the function used the global variable 'status_file'. In addition,
all functions that called xsddefault_read_status_data() and their ancestors
passed in the name of the main configuration file.

This commit fixes the semantics of the function so it is now passed the
name of the status file it actually reads.
Tests: test_events compiles again and runs, albeit not yet sucessfully

Created initialization function for shared configuration variables

This commit adds an initialization function for configuration variables
shared between core and the CGIs. The function is necessary because
one of the variables (and possibly more in the future) was pointing to
data segment memory, but depending on the path of execution, could be
free()'d. Such a path was occurring in one of the test modules. The
initialization function strdups that variable to prevent the messiness
that occurs when freeing data segment memory.
Tests: test_checks again passes all tests
Tests: test_logging again passes all tests
Corrected overzealousness in shared configuration variable initialization

Commit 3268e72f51b22e0780ef0f74f90d7bb9f5d610a1 created a shared
configuration variable initialization function, init_shared_cfg_vars(),
which was intended to initialize configuration variables shared between
Core and the CGIs. The function went too far and initialized some things
that are not configuration variables and caused problems (like preventing
daemon mode). This commit corrects that overzealousness.
