6673289944 Initialize local variable 
In `aztec_text_process`, `binary_string`, which aliases to `aztec`'s
`bit_pattern` has it's first element set to NUL. However, when the string
is later written into using `bin_append_posn`, that NUL is overwritten and
further NUL to replace it is not appended.

In general, the garbage collected memory content should never be assumed to
have a specific value unless a value was explicitly assigned, so the content
of `bit_pattern` cannot be safely assumed to be NUL.

If the string is not NUL terminated, functions relying on NUL termination,
such as the printf call at the end of `aztec_text_proccess` itself,
will overrun the array bounds.

Explicitly initialize `bit_pattern`

b3a1b24d18 help the compiler create more efficient code 
Patch from Michael <virtual_worlds@gmx.de>
Full text: As usual I have modified only minor things to remove warnigs when compiled as C++ code, have added some const-specifiers where possible to help the compiler create more efficient code and added some static-specifiers to make functions invisible to other modules.

It does not contain any fundamental changes or new functions but a lot of improvements which I have done over time (added several const/static specifiers, replaced repeated if-conditions by if-else, removed some warnings).
