Richard Levitte 9ba96fbb25 Perl's chop / chomp considered bad, use a regexp instead 
Once upon a time, there was chop, which somply chopped off the last
character of $_ or a given variable, and it was used to take off the
EOL character (\n) of strings.

... but then, you had to check for the presence of such character.

So came chomp, the better chop which checks for \n before chopping it
off.  And this worked well, as long as Perl made internally sure that
all EOLs were converted to \n.

These days, though, there seems to be a mixture of perls, so lines
from files in the "wrong" environment might have \r\n as EOL, or just
\r (Mac OS, unless I'm misinformed).

So it's time we went for the more generic variant and use s|\R$||, the
better chomp which recognises all kinds of known EOLs and chops them
off.

A few chops were left alone, as they are use as surgical tools to
remove one last slash or one last comma.

NOTE: \R came with perl 5.10.0.  It means that from now on, our
scripts will fail with any older version.

mkerr.pl [options] ...
Options:
-conf F Use the config file F instead of the default one:
crypto/err/openssl.ec
-hprefix P Prepend the filenames in generated #include <header>
statements with prefix P. Default: 'openssl/' (without
the quotes, naturally)
-debug Turn on debugging verbose output on stderr.
-rebuild Rebuild all header and C source files, irrespective of the
fact if any error or function codes have been added/removed.
Default: only update files for libraries which saw change
(of course, this requires '-write' as well, or no
files will be touched!)
-recurse scan a preconfigured set of directories / files for error and
function codes:
(<crypto/*.c>, <crypto/*/*.c>, <ssl/*.c>, <apps/*.c>)
When this option is NOT specified, the filelist is taken from
the commandline instead. Here, wildcards may be embedded. (Be
sure to escape those to prevent the shell from expanding them
for you when you wish mkerr.pl to do so instead.)
Default: take file list to scan from the command line.
-reindex Discard the numeric values previously assigned to the error
and function codes as extracted from the scanned header files;
instead renumber all of them starting from 100. (Note that
the numbers assigned through 'R' records in the config file
remain intact.)
Default: keep previously assigned numbers. (You are warned
when collisions are detected.)
-nostatic Generates a different source code, where these additional
functions are generated for each library specified in the
config file:
void ERR_load_<LIB>_strings(void);
void ERR_unload_<LIB>_strings(void);
void ERR_<LIB>_error(int f, int r, char *fn, int ln);
#define <LIB>err(f,r) ERR_<LIB>_error(f,r,__FILE__,__LINE__)
while the code facilitates the use of these in an environment
where the error support routines are dynamically loaded at
runtime.
Default: 'static' code generation.
-staticloader Prefix generated functions with the 'static' scope modifier.
Default: don't write any scope modifier prefix.
-unref Print out unreferenced function and reason codes.
-write Actually (over)write the generated code to the header and C
source files as assigned to each library through the config
file.
Default: don't write.
-help / -h / -? / --help Show this help text.
... Additional arguments are added to the file list to scan,
assuming '-recurse' was NOT specified on the command line.
