OAI is riddled with boolean_t, FALSE, TRUE, etc. This makes no sense, as there is a standard bool type, and could lead to nasty bugs if a definition of a bool is non-standard (0 == false, true == !false). This commit removes all non-standard bools in the whole project.

Description Implements the EPS Mobility Management procedures executed
|
|
when the EMM-SAP is in EMM-DEREGISTERED.LIMITED-SERVICE state.
|
|
|
|
In EMM-DEREGISTERED.LIMITED-SERVICE state, the EPS update
|
|
status is EU3, and it is known that a selected cell is unable
|
|
to provide normal service.
