Disabling debug/info output prevents compiling

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Undefine ENABLE_LOG_DEBUG and/or ENABLE_LOG_INFO in btstack-config.h
2. Build for POSIX daemon target

What is the expected output? What do you see instead?
Build fails with unused variable errors.

What version of the product are you using? On what operating system?
Compiling with gcc 4.8.3 on Linux.

When ENABLE_LOG_xxx isn't defined, then the log_xxx macros do nothing with 
their arguments. gcc detects that the arguments are unused, and the compile 
fails because -Wunused -Werror are in effect.

The attached patch defines a vararg function, __log_unused, which is a no-op. 
It is not used on embedded systems (to make sure that no string tables get 
compiled in by accident).
