initial close policy support

Added 'created' to the connectdata struct to hold the creation date, to
be used for the close policy decision

Curl_tvnow is now properly declared with (void)

curl_getinfo is removed, not a public function

added --random-file and --egd-file to the command line client

Added the two new seeding options

two new random seed options for the ssl config struct

two new random seed options: CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET

better chunked error detection

Added test case 36:
[HTTP GET with badly formatted chunked Transfer-Encoding]

updated the comment for the chunked reading

made it return illegal hex in case no hexadecimal digit was read when at
least one was expected

added an error code for illegal hex values in the chunked stream

Added new libcurl options in include/curl/curl.h, they're documented in
curl_easy_setopt.3 and they're partly implemented in lib/url.c

Slowly, we're getting there...

Added options for the persistant support, they're also documented in
curl_easy_setopt.3 now

support for a few new libcurl 7.7 CURLOPT_* options added

Added four new options that come with the new persitant support:
CURLOPT_MAXCONNECTS, CURLOPT_CLOSEPOLICY, CURLOPT_FRESH_CONNECT and
CURLOPT_FORBID_REUSE

the client is adjusted to work with persistant curl handles, and *gee* it
seems to be working!!!

Added infof() calls for persistant connection info, we are very likely to
need these at least for debugging 7.7 and probably later as well...

moved the libcurl init call

persistant updates

added a note about persitant connections through HTTP proxies

Added some persistant notes

modified to make the curl client with persistant connection support do
correct

include the failed test case numbers in the end summary
