Modified files:
	tools          : build-prc.cpp def.y palmdev-prep.c trapfilt.c 
	                 utils.c utils.h 

Log message:
Introduce file_length() and file_exists() utilities, and use them
instead of using raw struct stat in build-prc.cpp and palmdev-prep.c.
Using file_length(), slurp_file_as_datablock can now read directly
into its Datablock.

After that change, all the users of slurp_file() are using it to read
text files.  So replace it with slurp_text_file(), and implement that
so that it checks for EOF directly rather than checking that it read
exactly as many characters as it expected to.  This fixes a bug on
CR-LF filesystems where the number of characters read (which includes
\n characters) is less than the number of bytes in the file (which
includes CR-LF byte sequences).
