[Asterisk-code-review] astobj2: Declare private variable data size for AO2 DEBUG only. (asterisk[13])

[Corey Farrell]

Corey Farrell has uploaded a new change for review. ( https://gerrit.asterisk.org/4233 )

Change subject: astobj2: Declare private variable data_size for AO2_DEBUG only.
......................................................................

astobj2: Declare private variable data_size for AO2_DEBUG only.

Every ao2 object contains storage for a private variable data_size,
though the value is never read if AO2_DEBUG is disabled.  This change
makes the variable conditional, reducing memory usage.
