In preparation for adding a relative lock time type move the `locktime`
module to a new module called `absolute`. Use qualified path for
locktime types (e.g. `absolute::PackedLockTime`) to improve readability.

4a119e5624 Re-export blockdata modules (Tobin C. Harding)
Pull request description:
In an effort to make the library more ergonomic to use re-export modules from `blockdata` at the crate root level. This helps to decouple the internal code layout with the public API.

34f955a073 Introduce new canonical license blurb (Tobin C. Harding)
Pull request description:
Recently we introduced SPDX license ids but there was some confusion
about the use, form, and purpose of lines before (library name, author).
It was pointed out to me by Andrew that if/when folks cut'n'paste our
code they often will keep the whole blurb. Design it with that in
mind. FTR, Andrew also indicated that he did not mind his name being
removed in favour of "The rust-bitcoin developers".
At first I thought the term "The rust-bitcoin developers" was a bit
wishy-washy but yesterday I realised that I am proud to be part of that
crew, striving to deliver code to the highest possible standard.
Introduce a canonical format for the licences blurb.
- Use the name of the library
- Use "The rust-bitcoin developers"
- Use the SPDX ID

Turns out by default clippy does not lint certain parts of the public
API. Specifically, by setting
avoid-breaking-exported-api = false
we can get clippy to lint the public API for various things including
`wrong_self_convention`.
Clippy emits:
warning: methods with the following characteristics: (`to_*` and `self`
type is `Copy`) usually take `self` by value
As suggested, take `self` by value for methods named `to_*`.

`Sequence` didn't have `FromStr` nor `TryFrom<{stringly type}>`
implemented by accident. This moves a macro for implementing them from
`locktime` module to the `parse` module, renames it for clarity and uses
it to implement parsing for `Sequence`.
When debugging parsing errors it's very useful to know some context:
what the input was and what integer type was parsed. `ParseIntError`
from `core` doesn't contain this information.
In this commit a custom `ParseIntError` type is crated that carries the
one from `core` as well as additional information. Its `Display`
implementation displays this additional information as a well-formed
English sentence to aid users with understanding the problem. A helper
function parses any integer type from common string types returning the
new `ParseIntError` type on error.
To clean up the error code a bit some new macros are added and used.
New modules are added to organize the types, functions and macros.
Closes#1113
Add a `LockTime` type to hold the nLockTime `u32` value. Use it in
`Transaction` for `lock_time` instead of a `u32`. Make it public so this
new type can be used by rust-miniscript and other downstream projects.
Add a `PackedLockTime` type that wraps a raw `u32` and derives `Ord`,
this type is for wrapping a consensus lock time value for nesting in
types that would like to derive `Ord`.
