Use standard library calls like memset/memcpy for setting up BSS and DATA

The inline asm definition of irq_lock() on the ARM architecture marks
the ASM as volatile which prevents the compiler from removing the
isntruction but does provide any information to the compiler to
prevent the inline ASM instruction being re-ordered relative to other
instructions.  The instruction used in irq_lock() do not touch memory,
however in order to acheive their intended purpose they must be
ordered relative to other memory access instruction.  This is acheived
by adding the "memory" clobber.

Instances of the compiler inappropriately re-ordering irq_lock() calls
relative to other instructions without this patch can be observed in
the code generated for k_sleep() on NRF51 target boards.

getenv() returns an string of unknown size, so Coverity warns that it
might be used to overflow the stack in the call chain off
conf_read_simple().

To avoid that, wisdom says copy to an string of known size and pass
that.

The reversal of the meaning of a value of 0 from k_sem_take vs
nano_sem_take has caused some issue when porting code from the legacy
API to the new API, so put some emphasis on this difference.

- Add a note in the API description.
- Put the call to k_sem_take and the reversal of the return value inside
  of nano_sem_take on one line so that grepping on it shows the
  reversal.

This implements a modified version of CDC ACM class driver
in a WebUSB compatible way. It adds the WebUSB descriptors,
custom and vendor requests handlers so that the host OS and
browsers can get the required BOS descriptor and supported
origins from the device. It also adds a custom interface
class so that the interface will not be claimed by the host
CDC ACM driver.

A simple echo app also included in this commit to demonstrate
how to create and use a WebUSB interface, as well as the
communication between browser and WebUSB enabled device.

WebUSB Spec: https://wicg.github.io/webusb/



Origin: Based on CDC ACM device class driver in Zephyr

If a particular project needs to add additional data to the
binary image, in most cases the entire linker script needs to
forked into the project space, causing maintenance issues if
the main linker script is changed.

Now we add some Kconfig options to allow a project to specify
some additional linker scripts which get included by the main
one in a few key areas:

1) In the definition to the 'rodata' section, which can allow
additional data to be included in this ROM section.

2) In the definition to the 'datas' section, which allows
additional data to be included in this RAM section.

3) Arbitrary additional sections to be included at the end of
the binary.

For 1 and 2, this is useful to include data generated outside of
the normal C compilation, such as data structures that are created
by special build tools.

3 is useful for including arbitrary binary blobs inside the final
image, such as for peripheral or co-processor firmware.
