e1b1b79269 use gmtime_r() instead of gmtime() 
This avoids pulling in gmtime's static buffer:

d51ba0b5ab networking/interface.c: get rid of global data 
These were data/bss:

static.proc_read                                       1       -      -1

We never call display_interfaces() twice, thus code to not scan /proc twice
never triggers.

804ce5a6fe wget: fix fetching of https URLs with http proxy 
When fetching a https:// URL with HTTP proxy configured
(e.g. with environment variable http_proxy=http://your-proxy:3128)
busybox was making a https connection to the proxy.

This was because the protocol scheme for the target URL was used to determine whether to connect to the proxy over SSL or not.

When the proxy is in use, the decision on whether to connect to the proxy over https
should based on the proxy URL not on the target URL.
