Steven Scott 3130e8d3f1 Return write buffer to pool on write error (#427)
Fix bug where connection did not return the write buffer to the pool
after a write error. Add test for the same.

Rename messsageWriter.fatal method to endMessage and consolidate all
message cleanup code there. This ensures that the buffer is returned to
pool on all code paths.

Rename Conn.prepMessage to beginMessage for symmetry with endMessage.
Move some duplicated code at calls to prepMessage to beginMessage.

Bonus improvement: Adjust message and buffer size in TestWriteBufferPool
to test that pool works with fragmented messages.

Steven Scott cdd40f587d Add comprehensive host test (#429)
Add table driven test for handling of host in request URL, request
header and TLS server name. In addition to testing various uses of host
names, this test also confirms that host names are handled the same as
the net/http client.

The new table driven test replaces TestDialTLS, TestDialTLSNoverify,
TestDialTLSBadCert and TestHostHeader.

Eliminate duplicated code for constructing root CA.

Steven Scott b378caee5b Add write buffer pooling
Add WriteBufferPool to Dialer and Upgrader. This field specifies a pool
to use for write operations on a connection.  Use of the pool can reduce
memory use when there is a modest write volume over a large number of
connections.

Use larger of hijacked buffer and buffer allocated for connection (if
any) as buffer for building handshake response. This decreases possible
allocations when building the handshake response.

Modify bufio reuse test to call Upgrade instead of the internal
newConnBRW. Move the test from conn_test.go to server_test.go because
it's a serer test.

Update newConn and newConnBRW:

- Move the bufio "hacks" from newConnBRW to separate functions and call
these functions directly from Upgrade.
- Rename newConn to newTestConn and move to conn_test.go. Shorten
argument list to common use case.
- Rename newConnBRW to newConn.
- Add pool code to newConn.

Modify headers to match case used in RFC examples
Change the subprotocol and extension header names to match the case used
in RFC examples. Other headers names already match the case used in the
examples.

Although the headers names in the handshake are case insensitive, some
libraries expect the exact case used in the RFC examples. This change
allows the package to interoperate with those broken libraries.

Improve check origin documentation
Remove the example code to disable origin checks from the documentation.
I am concerned that developers are copying the code without
understanding the security implications of the code. Most applications
should not use this code.

Change the bad origin error message to mention Upgrader.CheckOrigin

Mention cross-site request forgery in the Upgrader.CheckOrigin doc.

Replace "frame" with "message" in documentation
The documentation sometimes used the term "frame" when referring to
single frame control messages.  Use the term "message" for consistency
in the documentation and to hide a detail that most application
programmers do not need to know about.

Handle no status in FormatCloseMessage
Return empty message for CloseNoStatusReceived. This status indicates
that the message is empty, so make it so. Because it's illegal to send
CloseNoStatusReceived, this change should not break a correct
application.

Add SOCKS5 support
- Bundle the golang.org/x/net/proxy package to x_net_proxy.go. The
package contains a SOCKS5 proxy. The package is bundled to avoid adding
a dependency from the weboscket package to golang.org/x/net.
- Restructure the existing HTTP proxy code so the code can be used as a
dialer with the proxy package.
- Modify Dialer.Dial to use proxy.FromURL.
- Improve tests (avoid modifying package-level data, use timeouts in
tests, use correct proxy URLs in tests).

Fixes #297.

Improve bad handshake error text
Change the error text for bad handshake errors from

    websocket: not a websocket handshake:

to:

    websocket: the client is not using the websocket protocol:

The new text should be more helpful to developers who do not know or
understand the details of the protocol.

Test for bad handshake before other request errors.

Sebastian Waisbrot 7ca4275b84 More consistent error handling in doc
I noticed the example is actually wrong as the same block both calls `return` with no parameter and `return err`. I think it would be better to allow the code to be used directly. I added calls to log.Println as it was used on the other example as it might be more useful for newcomers to see error messages.
