[Asterisk-code-review] ast careful fwrite to support EPIPE gracefully (asterisk[14])

[Kirill Katsnelson]

Kirill Katsnelson has uploaded a new change for review. ( https://gerrit.asterisk.org/4827 )

Change subject: ast_careful_fwrite to support EPIPE gracefully
......................................................................

ast_careful_fwrite to support EPIPE gracefully

When a reading end of the network socket is closed by an AMI manager,
the EPIPE is signaled when writing to our end, resulting in the
spurious log error message

  ast_careful_fwrite: fwrite() returned error: Broken pipe

Previously EPIPE was handled in ast_carefulwrite() a few lines above,
but not in this function.
