* Update r2 for dp fixes and general debug fixes
* Added ProcessesWidget for kernel debugging and switching between children
* Update r2 for dpl fixes
* Update r2 for linux and gdbserver dp/dp= fixes
* Added switchedThread and switchedProcess events to refresh their widgets
Seek doesn't always change after switching if the other process is at
the same offset in the same binary so it's better to have another event
for it.
* Disable threads/processes widget during a debugtask/when not debugging and clear it's history after a session
* Improve Processes Widget's UI
- Remove vertical numbers
- Highlight the current process with bold instead of using the "current"
column
* Updated r2 for fork fixes
