Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.
Also moves WebContentClient and the references to the generated IPC
descriptions, since they are all components of OutOfProcessWebView.
This patch has no functional changes.
Converts Help's layout to GML, propagates model and icon creation
errors, and switches to the MainWidget-namespace organization
pattern seen in more up-to-date apps like TextEditor to make things
easier to maintain going forward.
This is partially a revert of commits:
10a8b6d411561b67a1ad
Rather than adding the prot_exec pledge requried to use dlopen(), we can
link directly against LibUnicodeData in applications that we know need
that library.
This might make the dlopen() dance a bit unnecessary. The same purpose
might now be fulfilled with weak symbols. That can be revisted next, but
for now, this at least removes the potential security risk of apps like
the Browser having prot_exec privileges.
