Laurent Pinchart 2e4fc65f77 ipa: libipa: histogram: Fix typo
"weighted", derived from the verb "to weight", comes from Middle English
weight, weiȝte, weght, wight, from Old English wiht, ġewiht, from
Proto-Germanic *wihtiz, from Proto-Indo-European *weǵʰ-. In none of
those does the t come before the h.

Kieran Bingham 27aff949fb libcamera/base: Move extended base functionality
Move the functionality for the following components to the new
base support library:

 - BoundMethod
 - EventDispatcher
 - EventDispatcherPoll
 - Log
 - Message
 - Object
 - Signal
 - Semaphore
 - Thread
 - Timer

While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.

Jean-Michel HautboisandKieran Bingham 3ebb692f32 ipa: ipu3: Add a histogram class
This class will be used at least by AGC algorithm when quantiles are
needed for example. It stores a cumulative frequency histogram. Going from
cumulative frequency back to per-bin values is a single subtraction, while
going the other way is a loop.
