Not only in debug mode.

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.

Since String_getToken is not used anymore and currently only supports
a 50 char token, simply remove it for now.

It is possible to exceed the unsigned int data type on 64 bit systems
with enough available RAM. Use size_t in all places instead.
Proof of Concept: Create a 4 GB line in .htoprc file and run htop
$ dd if=/dev/zero bs=1024 count=4194304 | tr '\0' 'a' > ~/.htoprc
$ htop
Segmentation fault
Also avoid overflow of stack based "match" array in String_getToken.

Add helper function to reallocate an dynamic allocated array including
zeroing the newly allocated memory.

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:

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

Reduces code in callers and helps avoiding memory leaks.

The standard strncpy fails to null-terminate the destination in case
the source is longer than the passed size.

Like the C snprintf function

Inspired by proposed Linux syscall
Avoid file descriptor leaks like 4af8c63f

- Add Settings forward declaration in Process.h
- Add assert.h include in XUitls.c
- Add conditional stdbool.h include in Object.h
- Drop unneeded stddef.h include in Richstring.c
- Drop unneeded unistd.h include in Process.h
- Drop unneeded string.h include in linux/Platform.c
- Use String_eq to avoid string.h include in Action.c
- Improve script to run custom iwyu version

- 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

Allocating zero size memory results in implementation-defined behavior:
man:malloc(3) :
If size is 0, then malloc() returns either NULL, or a unique pointer
value that can later be successfully passed to free().

Information as seen by IWYU 0.12 + clang 9 on Linux

Avoids leaking memory upon realloc failure.
