u_boot_console.exec_attach.get_spawn() performs two steps:
1) Spawn a process to communicate with the serial console.
2) Reset the board so that U-Boot starts running from scratch.
Currently, if an exception happens in step (2), no cleanup is performed on
the process created in step (1). That process stays running and may e.g.
hold serial port locks, or simply continue to read data from the serial
port, thus preventing it from reaching any other process that attempts to
read from the same serial port later. While there is error cleanup code in
u_boot_console_base.ensure_spawned(), this is not triggered since the
exception prevents assignment to self.p there, and hence the exception
handler has no object to operate upon in cleanup_spawn().
Solve this by enhancing u_boot_console.exec_attach.get_spawn() to clean
up any objects it has created.
In theory, u_boot_spawn.Spawn's constructor has a similar issue, so fix
this too.

Implement three improvements to the HTML log file:
- Ability to expand/contract sections. All passing sections are contracted
at file load time so the user can concentrate on issues requiring
action.
- The overall status report is copied to the top of the log for easy
access.
- Add links from the status report to the test logs, for easy navigation.
This all relies on Javascript and the jquery library. If the user doesn't
have Javascript enabled, or jquery can't be downloaded, the log should
look and behave identically to how it did before this patch.
A few notes on the diff:
- A few more 'with log.section("xxx")' were added, so that all stream
blocks are kept within a section block for consistent HTML entity
nesting structure. This changed indentation in a few places, making
the diff look slightly larger.
- HTML entity IDs are cleaned up. We assign simple incrementing integer
IDs now, rather than using mangled test names which were possibly
invalid.
- Sections and streams now use common CSS class names (in addition to the
current separate class names) to more easily share the new behaviour.
This also reduces the CSS file size since rules don't need to be
duplicated.
- An "OK" status is logged after some external command executions so that
make and flash steps are auto-contracted at log file load time, assuming
they passed.

Python's coding style docs indicate to use " not ' for docstrings.
test/py has other violations of the coding style docs, since the docs
specify a stranger style than I would expect, but nobody has complained
about those yet:-)

This tool aims to test U-Boot by executing U-Boot shell commands using the
console interface. A single top-level script exists to execute or attach
to the U-Boot console, run the entire script of tests against it, and
summarize the results. Advantages of this approach are:
- Testing is performed in the same way a user or script would interact
with U-Boot; there can be no disconnect.
- There is no need to write or embed test-related code into U-Boot itself.
It is asserted that writing test-related code in Python is simpler and
more flexible that writing it all in C.
- It is reasonably simple to interact with U-Boot in this way.
A few simple tests are provided as examples. Soon, we should convert as
many as possible of the other tests in test/* and test/cmd_ut.c too.
The hook scripts, relay control utilities, and udev rules I use for my
own HW setup are published at https://github.com/swarren/uboot-test-hooks.
