r3.showdspf: fix null pointer dereference

In the current execution, when we face an error while trying
to open a database file, as part of error log we are dereferencing
a NULL file pointer (which is returend when we try to open a file).
Ideally we should be printing the name of the database file rather
than the file pointer. This fixes the problem of null pointer
dereference. Found via cppcheck tool.

color2 pointer is not initialized and it is assigned a value
depending on a conditional. Potentially, in an execution path
if conditional fails, we would be accessing an uninitialized
pointer, whose behavior is undefined. Initialize the pointer
to NULL to avoid this.

…_text for proj string (#4236)

Currently, if 'HAVE_OGR' macro is defined, as part of execution, we sort all formats by name using qsort. But, array containing all formats is assigned based on a conditional and if the conditional fails, it can be NULL.

Behavior of qsort when a NULL array is provided is undefined. To avoid getting into that situation, check if the array is NULL before performing qsort on it.

…e smaller than 0.0 (#4263)

Display pixels or raster region rows,cols are likely be on the order of 500, while projected map units are often in the millions, so pixels/meter factor can end up as a very small number. This patch edits an unused in the production code debug helper function to not round that division into a confusing 0.0, as well as some whitespace tweaks to make it more readable.

* docker: fix missing library in ubuntu wxgui Dockerfile

Add `libgtk-3-dev` to fix

```
...
checking for GTK+ - version >= 3.0.0... Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0' found
```

* also install 'python3-wxgtk4.0'

* lib: deprecate G_snprintf() and replace with C99 snprintf()

Beginning with UCRT in Visual Studio 2015 and Windows 10, the behaviour of snprintf (and vsnprintf) is now C99 standard conformant.

Thus, the output is now always null-terminated. The justification for a internal fix for that is no longer needed.

* r3.out.bin: fix -Werror=sizeof-pointer-memaccess GCC warning

* add support for Int8 from GDAL >= 3.7

* add int8 test (skiped if GDAL < 3.7)
