* 1. Concatenates a file extension to a passed filename,

|
* Moves the concatenated string to the passed buffer.
|
|
* 2. Checks for filename buffer overflow.

|
*
|
|
* replace_ext:
|
|
* Same thing, except that if a dotted extension is already
|
|
* provided, it REPLACES the last extension with the passed one.
