getinfo: add microsecond precise timers for various intervals
Provide a set of new timers that return the time intervals using integer
number of microseconds instead of floats.

The new info names are as following:

CURLINFO_APPCONNECT_TIME_T
CURLINFO_CONNECT_TIME_T
CURLINFO_NAMELOOKUP_TIME_T
CURLINFO_PRETRANSFER_TIME_T
CURLINFO_REDIRECT_TIME_T
CURLINFO_STARTTRANSFER_TIME_T
CURLINFO_TOTAL_TIME_T

.TH CURLINFO_APPCONNECT_TIME 3 "28 Aug 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
.SH NAME
CURLINFO_APPCONNECT_TIME \- get the time until the SSL/SSH handshake is completed
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME, double *timep);
.SH DESCRIPTION
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the SSL/SSH connect/handshake to the remote host was completed.
This time is most often very near to the \fICURLINFO_PRETRANSFER_TIME(3)\fP
time, except for cases such as HTTP pipelining where the pretransfer time can
be delayed due to waits in line for the pipeline and more.
See also the TIMES overview in the \fIcurl_easy_getinfo(3)\fP man page.
.SH PROTOCOLS
All
.SH EXAMPLE
.nf
curl = curl_easy_init();
if(curl) {
double connect;
curl_easy_setopt(curl, CURLOPT_URL, url);
res = curl_easy_perform(curl);
if(CURLE_OK == res) {
res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME, &connect);
if(CURLE_OK == res) {
printf("Time: %.1f", connect);
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
.fi
.SH AVAILABILITY
