Brandon W Maister 6622bdcae7 Replace all uses of `try!` with question mark
The `?` operator was stabilized in 1.13, this gets rid of a few hundred
deprecation warnings.

Fixes #357

Brandon W Maister b717e0442c Handle some semantic merge conflicts
Something that wasn't part of this PR: the work to support nested
`Option<[ChronoType]>` was merged without being adjusted for the no-std
support

And now there are some unused import warnings because they need to get
configged out.

Michal Srb f7318277e2 Simplify ITEMS in FromStr implementations
The Item::Space calls str::trim_left and Item::Numeric also calls
str::trim_left before doing anything else, so there is no need to
have Item::Space before Item::Numeric.

Speeds up parsing:

Michal Srb 05acc869b9 Accept Borrow<Item> as items
The parse::parse and format::format functions accepted Iterator of owned
Items. While it is sometimes convenient to pass in the owned values,
neither of the functions really need to own them, so references would
be enough. The Borrow trait allows us to pass in Iterator over values,
references, boxes, etc.

According to RFC 1105 this is a minor change, because it shouldn't break
any existing code. And chrono is in pre-1.0 version anyway.

This allows us to remove multiple cloned() calls which speeds up parsing
and formating:

Christopher Serr 9dc91f78ed Implement Support for no_std
This adds a new `std` feature to chrono that is enabled by default. By
deactivating this feature via `default-features = false` you can now use
chrono in applications that don't use the standard library. The `serde`
feature is supported as well.

Brandon W Maister 371cf6d29b Adjust timezones after doing Duration addition
The internal, tz-independent timestamp was valid, but since the timezone offset
could change as you add or subtract a second or two you would get
nonsense/nonexistent times when you observed them.

Brandon W Maister 39ca2e622c Deprecated warnings in cargo output for rustc-serialize feature
Unfortunately due to rust-lang/rust#39935 placing the annotation on the `impl`s
of `Encodable`/`Decodable` for the various items have no effect whatsoever, so
we need to place it on some type that chrono actually uses internally. The only
*type* that I can find that only exists for rustc-serialize only is the
 `TsSeconds` struct.

So, marking TsSeconds deprecated causes Chrono's internal uses of `TsSeconds`
to emit deprecation warnings, both in our builds and for packages that specify
Chrono as a dependency with the `rustc-serialize` feature active. This means
that the current commit will cause a `warning: use of deprecated item:
RustcSerialize will be removed before chrono 1.0, use Serde instead` to appear
in `cargo build` output.

Unfortunately I don't think that it's possible for downstream crates to disable
the warning the warning in any way other than actually switching to Serde or
using an older chrono. That's the reason for all the `#[allow(deprecated)]`
through the code, it means that the warning appears almost exactly once,
instead of dozens of times.

David Kellum d2bf1494b1 Add DateTime to_rfc3339p(z) methods, tests
These additions allow convenient control of RFC 3339 formatted output:

 * Number of subsecond digits to display

 * Whether to use the 'Z' variant, instead of "+00:00" for TZ offset
   0, UTC.

...while remaining faithful to the RFC 3339. The implementation uses
the existing formatting Item mechanism.

David Kellum 9742ecccc5 Allow (clippy) needless_pass_by_value on signed_duration_since
Current clippy is probably correct, but its a breaking change that
isn't appropriate now. Add allow's to get the build working again.

Also these Date(Time)::signed_duration_since cases appear to match
there `Naive` counterparts, where clippy isn't complaining. If its
fixed in the future, should probably be changed across the board, not
just here.

Brandon W Maister 5bb493976b Add a note and example to DateTime::parse_from_str
The note points out that `NaiveDateTime::parse_from_str` is required if you
don't know the offset, and the example demonstrates that.

Added `From` implementations between `SystemTime` and `DateTime`.
Due to the obvious lack of time zone information in `SystemTime`,
`SystemTime` can only be converted to `DateTime<Utc>` (in UTC) or
`DateTime<Local>` (in the local time zone), while any `DateTime<Tz>`
can be converted to `SystemTime`.

Kang Seonghoon 9768b289f0
New type: `chrono::naive::IsoWeek`.
This removes `Datelike::isoweekdate` in favor of `Datelike::iso_week`.
The original `isoweekdate` was not named in accordance with the style
guide and also used to return the day of the week which is already
provided by `Datelike::weekday`. The new design should be more
reasonable.

Note that we initially do not implement any public constructor for
`IsoWeek`. That is, the only legitimate way to get a new `IsoWeek` is
from `Datelike::iso_week`. This sidesteps the issue of boundary values
(for example the year number in the maximal date will overflow in
the week date) while giving the same power as the original API.

Partially accounts for #139. We may add additional week types
as necessary---this is the beginning.
