Api changes :
- removeLastPathElement do not takes extra arguments
`removePreSeparator` and `removePostSeparator`.
This is not needed as path do not need special tailing separator.
- Only one function `split`. Arguments can be implicitly convert to
string. No need for overloading functions to explicitly cast them.
- `split` function takes another argument `trimEmpty`. If true, empty
element are removed.
Path manipulation now almost pass trough a vector<string> to store each
path's part.
Most of the complex works is now made in the normalizeParts function.
There are two executable path :
- The user one (the appimage path)
- The real one (in the appimage archive)
When we search of `library.xml` we need the user one.
But when we search of `aria2c` or `kiwix-serve` we need the real one.
Fixkiwix/kiwix-desktop#256
They are not used at all and the windows version need some extra libs
that complexify the code.
Remove them for now. If it happens that they are needed, we will readd
them.
The `common` name is from the time where kiwix was only one repository
for all the project (android, desktop, server...).
Now we have split the repositories and kiwix-lib is the "common" repo,
the "common" directory is somehow nonsense.
