Andrew Dunham 38e4d303a2 net/tshttpproxy: don't proxy through ourselves
When running a SOCKS or HTTP proxy, configure the tshttpproxy package to
drop those addresses from any HTTP_PROXY or HTTPS_PROXY environment
variables.

Fixes #7407

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Brad Fitzpatrick fb392e34b5 net/tshttpproxy: don't ignore env-based HTTP proxies after system lookups fail
There was a mechanism in tshttpproxy to note that a Windows proxy
lookup failed and to stop hitting it so often. But that turns out to
fire a lot (no PAC file configured at all results in a proxy lookup),
so after the first proxy lookup, we were enabling the "omg something's
wrong, stop looking up proxies" bit for awhile, which was then also
preventing the normal Go environment-based proxy lookups from working.

This at least fixes environment-based proxies.

Plenty of other Windows-specific proxy work remains (using
WinHttpGetIEProxyConfigForCurrentUser instead of just PAC files,
ignoring certain types of errors, etc), but this should fix
the regression reported in #4811.

Updates #4811

net/tshttpproxy: support basic auth when available (#1354)
This allows proxy URLs such as:

    http://azurediamond:hunter2@192.168.122.154:38274

to be used in order to dial out to control, logs or derp servers.
