Daniel Lange 7c43e02591 Improve String_contains_i to allow for multiple terms
This enables:
* Multiple filters in the main panel and strace etc. views
* Multiple search terms

The search terms are separated by "|" and are still fixed strings
matched case-insensitive.

Added a multi flag at request of BenBE.

Tobias Stoeckmann a133ffd829 Removed unused String_getToken function
Since String_getToken is not used anymore and currently only supports
a 50 char token, simply remove it for now.

Christian Göttsche c243db0b2c XUtils: move implementation of String_contains_i out of header file
The function strcasestr(3) is only available if _GNU_SOURCE is defined.
If any file includes <string.h> before declaring _GNU_SOURCE, e.g by
including "config.h", compilation fails with the following error:

    In file included from ColumnsPanel.c:8:
    In file included from ./ColumnsPanel.h:12:
    In file included from ./Panel.h:13:

       return strcasestr(s1, s2) != NULL;
              ^
    ./XUtils.h:42:11: note: did you mean 'strcasecmp'?

    extern int strcasecmp (const char *__s1, const char *__s2)
               ^

Move the implementation to avoid unnecessary includes.
Since LTO is quite common and stable performance should not be impacted
if used.

Christian Göttsche 4c66eb6d4c XUtils string related updates
- allow count out-parameter of String_split() to be NULL
- introduce xStrndup()
- do not allow NULL pointers passed to String_eq()
  it is not used in any code
- implement String_startsWith(), String_contains_i() and String_eq()
  as inline header functions
- adjust several conversion issues
