This commit fixes a memory corruption bug when parsing lines of the
form:
-x FOO=bar
The code was making changes to the size of the buffer allocated for
key_buffer without making the appropriate changes to
key_buffer_len. This was causing subsequent calls to save_param_name
to write to invalid memory.
This commit makes the following changes:
- Fix the above bug by modifying trim_name to move the string within
the buffer instead of re-allocating space for the trimmed string.
- Cleaned up both trim_name and save_param_name. Both functions took
a prefix and suffix to trim. Problem was the prefix was not
treated like a prefix. Instead the "prefix" was located inside the
string using strstr then the trimmed value started after the
substring (even in the middle of the string). To allow trimming
both -x and --x (as well as -mca and --mca) trim_name is now
called with each prefix.
