[Asterisk-code-review] res_config_odbc: set empty extended field as a single whitespace (...asterisk[16])

[Alexei Gradinari]

Hello Friendly Automation, George Joseph, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/11163

to look at the new patch set (#2).

Change subject: res_config_odbc: set empty extended field as a single whitespace
......................................................................

res_config_odbc: set empty extended field as a single whitespace

If Realtime @ variable value is NULL or empty or contains only whitespaces
then when we try to retrieve it using PJSIP_ENDPOINT we get WARNING
pjsip_endpoint_function_read: Unknown property @my_var for PJSIP endpoint.
And the variable is missing in the result of CLI pjsip show endpoint.

This patch keeps empty sorcery extended field.

ASTERISK-28341 #close
