Added curl_easy_getinfo.3

added a small suggestion on how to get the curl man page in text format
without nroff

Uses the new "client-side" writeout function

removed writeout.[ch] and added getinfo.c

Added writeout.c

writeout.[ch] added in src/

moved out from the library and put here, uses the new curl_easy_getinfo()

adjusted for curl_easy_getinfo

getinfo.c replaces the former writeout.c

Added curl_easy_getinfo()

#include <malloc.h> was removed, it causes warnings on openbsd

include base64.h instead of base64_krb.h

7.3 commit

replaced the old base64 stuff with the new ones

more configure options explained

a --krb4 usage example added

added krb4-info

Added strlcpy() since it turns out some krb4-implementations don't include
their own, even if mine did!

moved the RAND_status() and RAND_screen() checks to the openssl section
added strlcpy() check in the krb4 section

CRYPTO_free() of course, it makes it run with previous openssl versions too

The last week's changes

-c and -t is no longer prefered

corrected curl_write() for kerberos

Martin Hedenfalk added sec_fflush_fd()

krb4 transfers get a sec_fflush_fd() to get uploads to work
