Add Func log method (#321)
This adds the Func log method to log using an anonymous function
only if the level is currently enabled.

The use case is for when you don't own an object and therefore can't
create your own marshaller but need to do some translation prior to
logging.

For example, this:

msg := log.Debug()
if msg.Enabled() {
  msg.Str("complicated_thing", makeBinaryThingLoggable(thing))
}
msg.Msg("Sending complicated thing")

Turns into this:

log.Debug().
  Func(func(e *Event) { e.Str("complicated_thing", makeBinaryThingLoggable(thing)) }).
  Msg("Sending complicated thing")

Zephaniah Loss-Cutler-Hull 4de2fcc128
Fix handling of printing caller with Write, Print, and Printf. (#315)
* Add event.CallerSkipFrame(skip int)

This indicates that, for this event, we should skip an additional
specified number of frames.

This is cumulative, calling it twice for the same event will add both
numbers together, and this is in addition to any skip frame settings set
through the context, or globally.

The indended purpose is for wrappers to Msg or Msgf, so that the actual
caller is always printed correctly.

* Use CallerSkipFrame for Print, Printf, and Write.

This allows us to use the correct caller when using these 3 functions.

guonaihong e709c5d91e Allow custom caller level (#196)
To modify the Caller, you can pass a jump to a few function call stacks.

```go
package main

import (
    "github.com/rs/zerolog"
    "github.com/rs/zerolog/log"
)

func myError() {
    log.Debug().Caller(1).Str("test2", "v2").Send()
}

func foo() {
    log.Debug().Caller(2).Str("test2", "v2").Send()
}

func myError2() {
    foo()
}
func main() {
    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix

    log.Debug().Caller().Str("test1", "v1").Send()
    myError()
    myError2()
}
```

Olivier Poitrey e0f8de6c35 Fix usage of sync.Pool
The current usage of sync.Pool is leaky because it stores an arbitrary
sized buffer into the pool. However, sync.Pool assumes that all items in the
pool are interchangeable from a memory cost perspective. Due to the unbounded
size of a buffer that may be added, it is possible for the pool to eventually
pin arbitrarily large amounts of memory in a live-lock situation.

As a simple fix, we just set a maximum size that we permit back into the pool.

The Discard method has been added to the Event type so it can be called

Dušan Kasan 1c6d99b455 Add custom error serialization support and provide sane defaults (#78)
As per https://github.com/rs/zerolog/issues/9 and to offer a different approach from  https://github.com/rs/zerolog/pull/11 and https://github.com/rs/zerolog/pull/35 this PR introduces custom error serialization with sane defaults without breaking the existing APIs.

This is just a first draft and is missing tests. Also, a bit of code duplication which I feel could be reduced but it serves to get the idea across.

It provides global error marshalling by exposing a `var ErrorMarshalFunc func(error) interface{}` in zerolog package that by default is  a function that returns the passed argument. It should be overriden if you require custom error marshalling.

Then in every function that accept error or array of errors `ErrorMarshalFunc` is called on the error and then the result of it is processed like this:
- if it implements `LogObjectMarshaler`, serialize it as an object
- if it is a string serialize as a string
- if it is an error, serialize as a string with the result of `Error()`
- else serialize it as an interface

The side effect of this change is that the encoders don't need the `AppendError/s` methods anymore, as the errors are serialized directly to other types.
