We have a few places where we read secrets into memory, and then
do some computation on them. In these cases we should always make
sure we zero the allocations before they are free'd.
The SecureString wrapper provides this abstraction by wrapping a
ByteBuffer and calling explicit_bzero on destruction of the object.
`ArgsParser` and `AboutDialog` had the same procedure to read the
version from `/res/version.ini`. Now they use the `SERENITY_VERSION`
string by default.
This commit refactored the version-reading utility to the new
`Core::Version` namespace.
This is a simple wrapper around posix_spawn() that will help us simplify
a bunch of very verbose posix_spawn() invocations.
This first version only supports the simplest case: executing an
executable without passing arguments or doing anything fancy. More
features can be added to cover more cases. :^)
This commit removes the only 3rd party library (and its usages)
in serenity: puff, which is used for deflate decompression. and
replaces it with the existing original serenity implementation
in LibCompress. :^)
This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.
Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.
