[autofit] Introduce data file for blue strings.
The idea is to have a central file which gets processed by a Perl
script to create proper `.c' and `.h' files using templates. There
are two other reasons to do that:
. The data file should be easily readable. We use UTF-8 encoding
which then gets converted to single bytes.
. Since the number of supported scripts will increase soon, the
current usage of blue string arrays is a waste of space. Using
the Perl script it is possible to imitate jagged arrays,
defining enumeration constants as offsets into the arrays.
This commit only adds files without changing any functionality.
* src/autofit/afblue.dat: New data file.
* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files
for...
* src/autofit/afblue.c, src/autofit/afblue.c: New source files.
To avoid a dependency on Perl, we add them too.

+// This file contains data specific to blue zones. It gets processed by
+// a script to simulate `jagged arrays', with enumeration values holding
+// offsets into the arrays.
+//
+// The format of the file is rather simple: A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template, holding the size of the largest array element. The
+// script then fills the corresponding templates (indicated by `@'
+// characters around the name).
+//
+// A section contains one or more data records. Each data record consists
+// of two or more lines. The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters in UTF-8 encoding enclosed in double quotes,
+// using C syntax. There can be only one string per line, thus the
+// starting and ending double quote must be the first and last character
+// in the line, respectively, ignoring whitespace before and after the
+// string. If there are multiple strings (in multiple lines), they are
+// concatenated to a single string. In the output, a string gets
+// represented as a series of singles bytes, followed by a zero byte. The
+// enumeration values simply hold byte offsets to the start of the
+// corresponding strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+// which can span multiple lines. The opening brace of a block must be
+// the first character of a line (ignoring whitespace), and the closing
+// brace the last (ignoring whitespace also). The script appends a comma
+// character after each block and counts the number of blocks to set the
+// enumeration values.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed. A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array. Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum
+// values; this essentially means that the maximum values can easily be too
+// large. Given that the purpose of those values is to create local
+// fixed-size arrays at compile time for further processing of the blue zone
+// data, this isn't a problem. Note the the final zero byte of a string is
+// not counted. Note also that the count holds the number of UTF-8 encoded
+// characters, not bytes.
