There have been some revamping of the Rand API. The Standard
distribution on floating point numbers will return a value in the
interval [0,1).

Updates a few sim dependencies, reducing the amount of crates
required for a build; also gets rid of cases of more than one
version required for some crates. Results in depending on 76
crates instead of 89 before the PR.

Add an apache SPDX header and explicit license lines. The date ranges
of the license lines is derived from the git history. Having these
explicitly present will make contributions from other parties easier, as
they will simply be able to add their own copyright line, rather than
having to describe that it only covers modifications.

Ran automated checker for common typos [1]. Most of these changes have
no functional change *except* for `./ci/sim_run.sh` where, previously
the `bootstrap` feature wasn't being selected properly.
I didn't touch anything in the `./ext/` folder as anything in there
should probably be fixed in the upstream repo.

The Rust community has decided that 'failure' is the future, instead of
'error-chain'. Migrate the flash simulator to this new error handling
package. The changes are relatively minor, and the end result is a
similar `FlashError` type.

The name `SimFlashMap` is a bit misleading, as the Map part is more of
an implementation detail when the type really just represents multiple
flash devices.
This is just a rename, but the names `SimFlashMap` and the value
`flashmap` occur in a lot of places in the image module.

Since logging was broken due to incompatibility between log and
env_logger versions, those crates were updated to known to be compatible
versions. Update initialization of env_logger that does not return a
Result<> anymore.
Other crates were updated to remove duplicated versions as much as
possible.

Apply the changes suggested by
cargo fix --edition-idioms
as well as a bit of cleanup of the results. The result should be more
idiomatic Rust 2018 and a good starting point moving forward.

Automatic migration to Rust 2018. This is the result of running
cargo fix --edition
The resulting code is compatible with both Rust 2015 and 2018. Change
the edition field in the Cargo.toml file as well to begin a more
complete migration.

This adds an initial device with multiple flash (nrf52840 + SPI flash)
and updates all test routines to use a HashMap of flash devices (added
as type SimFlashMap).
Signed-off-by: Fabio Utzig <utzig@apache.org>
A new type `FlashMap` that stores a HashMap of [device_id -> Flash trait]
was added, which enables multi-flash devices to be passed around.
The previously existing static FLASH value that was used to simulate the
raw device, was updated to using a FlashMap which enables bootutil to
interface with more than one flash device.

A new align() function was added to SimFlash, and most functions that
were using/receiving align or erased_val parameters that had access to a
Flash trait were cleaned up so that they get the parameters directly
from the Flash device.
This will make it easier to extend for multiple Flash devices since
parameters should depend on the device in use.

This extends the simulator to be able to test the bootloader in devices
which use flash technologies that erase flash at 0 instead of 0xff.
Two MCU devices that have this "property" are the STM32L0x and STM32L1x
lines from ST.

Move to newer versions of some upstream packages, lazy_static, which is
now at 1.0 (no api change), and error-chain (0.11), which eliminates a
warning during compilation.

At the moment writes always checking that they are being
performed on an erased section of memory. This patch enables
a test to disable that, to enable looking for other error

Add new interface to enable configuring regions of the simulated
memory to fail probabilistically. An entry is based on an offset,
length and rate of failure. This only applies to write operatios
and throws an error that can be caught in tests.

In preparation for moving the bootutil binding into a separate crate,
move the flash simulator into its own crate. This will allow the
binding to have access to the simulator without creating a circular
dependency.
