…er not to struct

allow ptr in inline structs

I've added a use for os.Kill, instead of os.Interrupt signal, when using
Windows. I'm current developing my project on Windows, and using
DBServer.Stop() was resulting in: "timeout waiting for mongod process to
die". After investigating, I've discovered that os.Interrupt isn't
implemented on Windows, and it seems golang has Frozen this issue due to
age (2013). They instruct to use os.Kill instead. Using this, the
DBServer on my project works with no problem.

* socket: only send client metadata once per socket (#105)

Periodic cluster synchronisation calls isMaster() which currently resends the
"client" metadata every call - the spec specifies:

	isMaster commands issued after the initial connection handshake MUST NOT
	contain handshake arguments

	https://github.com/mongodb/specifications/blob/master/source/mongodb-handshake/handshake.rst#connection-handshake

This hotfix prevents subsequent isMaster calls from sending the client metadata
again - fixes #101 and fixes #103.

Thanks to @changwoo-nam @qhenkart @canthefason @jyoon17 for spotting the initial
issue, opening tickets, and having the problem debugged with a PoC fix before I
even woke up.

* Merge Development (#111)

* Brings in a patch on having flusher not suppress errors. (#81)

go-mgo#360

* Fallback to JSON tags when BSON tag isn't present (#91)

* Fallback to JSON tags when BSON tag isn't present


Cleanup.

* Add test to demonstrate tagging fallback.

- Test coverage for tagging test.

* Cluster abended test 254 (#100)

* Add a test that mongo Server gets their abended reset as necessary.

See https://github.com/go-mgo/mgo/issues/254 and
https://github.com/go-mgo/mgo/pull/255/files

* Include the patch from Issue 255.

This brings in a test which fails without the patch, and passes with the
patch. Still to be tested, manual tcpkill of a socket.

* changeStream support (#97)

Add $changeStream support

* readme: credit @peterdeka and @steve-gray (#110)

* Hotfix #120  (#136)

* cluster: fix deadlock in cluster synchronisation (#120)

For a impressively thorough breakdown of the problem, see:
	#120 (comment)

Huge thanks to @dvic and @KJTsanaktsidis for the report and fix.

* readme: credit @dvic and @KJTsanaktsidis

* added support for marshalling/unmarshalling maps with non-string keys

* refactor method receiver

* added support for json-compatible support for slices and maps Marshal() func: nil slice or map converts to nil, not empty (initialized with len=0)

* fix IsNil on slices and maps

format

* added godoc

* fix sasl empty payload

* fix scram-sha-1 auth

* revert fix sasl empty payload

* socket: separate read/write network timeouts

Splits DialInfo.Timeout (defaults to 60s when using mgo.Dial()) into ReadTimeout
and WriteTimeout to address #160. Read/write timeout defaults to
DialInfo.Timeout to preserve existing behaviour.

* cluster: remove AcquireSocket

Only used by tests, replaced by the pool-aware acquire socket functions:
	* AcquireSocketWithPoolTimeout
	* AcquireSocketWithBlocking

* cluster: use configured timeouts for cluster operations

* `mongoCluster.syncServer()` no longer uses hard-coded 5 seconds
* `mongoCluster.isMaster()` no longer uses hard-coded 10 seconds

* tests: use DialInfo for internal timeouts

* server: fix fantastic serverTags nil slice bug

When unmarshalling serverTags, it is now an empty slice, instead of a nil slice.

`len(thing) == 0` works all the time, regardless.

* cluster: remove unused duplicate pool config

* session: avoid calculating default values in hot path

Changes `DialWithInfo` to handle setting default values by setting the relevant
`DialInfo` field, rather than calling the respective methods in the hot path for:

	* `PoolLimit`
	* `ReadTimeout`
	* `WriteTimeout`

* session: remove unused consts

* session: update docs

* add URI options: "w", "j", "wtimeoutMS"

* change "w" to "j"

The documentation now explains the difference between calling Err and
Close after Next returns false.

The example code has been expanded to include checking for timeout.

code is inspired by go-mgo#202
