discover: Remove unused params.c
The discover/params code is an artifact from a long time ago, and isn't used by anything today: remove it. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>

- * Module name: params
- *
- * -------------------------------------------------------------------------- **
- *
- * This module performs lexical analysis and initial parsing of a
- * Windows-like parameter file. It recognizes and handles four token
- * types: section-name, parameter-name, parameter-value, and
- * end-of-file. Comments and line continuation are handled
- * internally.
- *
- * The entry point to the module is function pm_process(). This
- * function opens the source file, calls the Parse() function to parse
- * the input, and then closes the file when either the EOF is reached
- * or a fatal error is encountered.
- *
- * A sample parameter file might look like this:
- *
- * [section one]
- * parameter one = value string
- * parameter two = another value
- * [section two]
- * new parameter = some value or t'other
- *
- * The parameter file is divided into sections by section headers:
- * section names enclosed in square brackets (eg. [section one]).
- * Each section contains parameter lines, each of which consist of a
- * parameter name and value delimited by an equal sign. Roughly, the
- * syntax is:
- *
- * <file> :== { <section> } EOF
- *
- * <section> :== <section header> { <parameter line> }
- *
- * <section header> :== '[' NAME ']'
- *
- * <parameter line> :== NAME '=' VALUE '\n'
- *
- * Blank lines and comment lines are ignored. Comment lines are lines
- * beginning with either a semicolon (';') or a pound sign ('#').
- *
- * All whitespace in section names and parameter names is compressed
- * to single spaces. Leading and trailing whitespace is stipped from
- * both names and values.
- *
- * Only the first equals sign in a parameter line is significant.
- * Parameter values may contain equals signs, square brackets and
- * semicolons. Internal whitespace is retained in parameter values,
- * with the exception of the '\r' character, which is stripped for
- * historic reasons. Parameter names may not start with a left square
- * bracket, an equal sign, a pound sign, or a semicolon, because these
- * are used to identify other tokens.
