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 Defines the ESM status procedure executed by the Non-Access
|
|
Stratum.
|
|
|
|
ESM status procedure can be related to an EPS bearer context
|
|
or to a procedure transaction.
|
|
|
|
The purpose of the sending of the ESM STATUS message is to
|
|
report at any time certain error conditions detected upon
|
|
receipt of ESM protocol data. The ESM STATUS message can be
|
|
sent by both the MME and the UE.
