If the config file does not exist and the force flag is not set,
OpenFile would not use O_CREATE flag, causing viper to fail with
error "File not exist" and to not create the config file.
This patch changes the behavior of writeConfig() so that if force is set
to false, OpenFile will use O_EXCL flag, thus failing if the file
already exists or creating a new file otherwise.

Defering can cause trouble because we're writing to the file outside the function
where the defering is registered, calling f.Sync() ensures that bytes are flushed
to disk even is Close() is called too soon.
* Added a new `DecoderConfigOption` type allowing the user to write custom
functions that can override the default mapstructure.DecoderConfig
settings
* Added a new `DecodeHook` function which returns
a `DecoderConfigOption`. This allows the user to easily set their own
Decode hooks when Unmarshaling
* Updated Unmarshal, UnmarshalKey and defaultDecoderConfig to support variadic
trailing `DecoderConfigOption` functions to allow for customisation of
the default mapstructure.DecoderConfig
* Added a test case with example usage
Support override of symlink to config file
Include tests for WatchConfig of regular files, as well
as config file which links to a folder which is itself a
link to another folder in the same "watch dir" (the way
Kubernetes exposes config files from ConfigMaps mounted
on a volume in a Pod)
Also:
- Add synchronization with WaitGroup to ensure that the WatchConfig
is properly started before returning
- Remove the watcher when the Config file is removed.
Fixes#284

* Added method to write into TOML file.
* Added functionality to export configuration based on config type. The feature supports JSON and TOML.
* Added method to write into YAML file.
* Fixed the issue of incorrect defer and error checking order. The error checking must be first otherwise it will cause panic.
* Add WriteConfig methods
* Add support for toml
* Add shared write function and safe methods
* Fix incorrectly modified imports
* Remove extra comments
* Fix spelling
* Make marshal spelling consistent throughout
* Add support for remaining configuration types
This commit moves a significant portion of the code back to viper.go to
facilitate having access to the object when reading the files. The purpose is to
add properties to the viper object at read time, so that we can add the comments
back to the file when writing.
* Add tests for each written file type
* Modify test for updated HCL specification
* Modify to only support HCL write in Go 1.7
* Revert "Modify to only support HCL write in Go 1.7"
This reverts commit 12b34bc4eb92cbf8ebfd56b79519f448607e3e51.
* Need to truncate the file before writing
* Write all settings including overrides
* Use filename variable
* Lint remote.go
* Fix toml return count error
If the user creates a invalid config file while watching for config
changes, the previous, valid config is not retained. This commit only
overwrites the running config if unmarshalling was successful.
