Brandon W Maister b553798f86 Support -0000 as a valid UTC tz in rfc2822
This is a time that is commonly set in some environments, and RFC 5322
explicitly clarifies that we should treat -0000 as UTC[1][2] when interpretting
rfc2822.

Fixes #102

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 6da5359d39 Reimplement scan::number
The original would first check that there is right amount of numeric
characters and then parsed them using the std::str::parse, which
internally checks the characters again and also checks for -/+ prefix,
which is not necessary in this case.

Since we are already going over the characters, we may as well do the
parsing ourselves. The length of the function is roughly the same and
it is faster:

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:

 name                                                 control ns/iter  remove-cloned ns/iter  diff ns/iter   diff %  speedup

 datetime::tests::bench_datetime_parse_from_rfc3339   242              239                              -3   -1.24%   x 1.01

Brandon W Maister a74a9744f1 Remove num_days_from_epoch
Deciding between zero-indexed (slightly more reasonable, more compatible with
the outside world) and one-indexed (same indexing as `num_days_from_ce`) seems
not worth it. It's trivial to build `num_days_from_epoch` based on the docs in
`num_days_from_ce`, which punts on the decision and is therefor probably the
right decision.

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

nonsense/nonexistent times when you observed them.
