Gisle Vanem's IPv6-on-Windows patch applied!

allow out-of-memory testing by setting a limit. That number of memory
allocation calls will succeed, the following will return NULL!

use CURLDEBUG instead of MALLOCDEBUG for preprocessor conditions

removed the local variables for emacs and vim, use the new sample.emacs
way for emacs, and vim users should provide a similar non-polluting style

copyright year update in the source header

updated source code boilerplate/header

James Cone's efforts to add another netrc parsing "mode"

copyright string (year) update

detect fclose(NULL)

more fancy alloc, we store the size in each allocated block so that we
can destroy the full allocated area just before we free it

always allocates at least 64 bytes for real, and damages them before free

Nico Baggus' VMS tweaks

fill memory with junk on malloc()

the malloc debug system only logs data if the logfile FILE * is set, which
makes it easier to disable debug output when built with debug functions

looks nicer and is better compatible with older vim versions

Added formatting sections for emacs and vim

curl_memdebug takes a const argument now

const-ified lots of function arguments

uses socklen_t now

strdup() takes a const char * now

Internal symbols that aren't static are now prefixed with 'Curl_'

dual-license fix

include unistd.h if present to prevent compiler warnings on close()

Added fopen() and fclose() leak tracking

fixed accept() for memory debugging
