A recent change in glibc 2.42.9000 [1] changes the return type of
strstr() and other string functions to be 'const char *' when the
input is a 'const char *'.
This breaks the build in various files with errors such as :
error: initialization discards 'const' qualifier from pointer target type
[-Werror=discarded-qualifiers]
208 | char *pidstr = strstr(filename, "%");
| ^~~~~~
Fix this by changing the type of the variables that store the result
of these functions to 'const char *'.

Most changes are straight forward apart from vubr_parse_host_port.
Please check.
Thanks,
