  [core] Fix wording.
  [core] Cleanup error reporting.

* core-help:
  [core] Simplify tests.
  [core] Align help to fit 80 chars. Add more tests. Fix indening.

  [core] Implement command options parsing via gopt.
  [core] Enable --help switch.

Merge with the master (new version of the test-runner).
Fix failing tests.

Post-review fixes: realign help text to match
exactly GNU tools (21st column), reorder help
messages to provide most relvant options first,
edit help text, print values for default options.

Style edits of gopt option library:
add API comments, remove trailing spaces.

Fir a formatting bug accidentally introduced by
the previous patch.

Provide better diagnostics when we can't even enter
the directory where we expect to find the server binary.

Add coverage for (almost) all admin options.
@todo: test 'exit'

Add coverage for more test options.
Make test results more host-independent.

Extend lib/test_suite.py: if we filtered out
entire line from the result, don't write newline
to the result file.

Split results from .test files into
.result files. Make each individual test a
small python program, which is executed from the context
of the main interpreter. This allows for easy access to
interpreter environment, such as the currently running
server.

Implement a pre-processor for .test files that replaces

exec admin <expr>
and
exec sql <expr>

with python syntax that actually sends string <expr>
to tarantool server connection (lib.admin.Connection), and
prints output to stdout (i.e. .reject file).

Implement stdout filters, for use in .test files:
this enables testing of statement that produce
run-dependent or host-dependent results.

Remove 'cmd' suite as unnecessary, args.test is moved
to box.suite. @todo: make results of the test host-independent.

Fix a bug in lib.admin.Connection (administrative connection)
when it would block and indefinitely wait for response for
some administrative commands.

Add test/lib/ for python modules.
Create the first module that implements
admin connection.
Automatically read host and port
and pidfile from tarantool configuration
file, and thus remove them from suite.ini.
Change .gitignore and remove a too
broad ignore mask (it ignored __init__.py,
which is mandatory file name for a module
in python).
Fix a bug in config reader for tarantool
that would leave "box.pid" in quotes.
Move TestSuite and Test to a lib/ module.
Patch cmdline.py and ./admin.py to
read input in line-buffered fashion (used
to be block-buffered), regardless of whether
input is a terminal or a pipe. This allows to
work with these tools interactively.

Update silverbox protocol description to use BNF.
Add more comments.
Explain semantics of protocol fields and restrictions
on field content.

Explain semantics of protocol fields and restrictions

When called from a non-default location (non-working directory),
print usage, tell where to invoke the program from, and bail
out.

Add a new test suite, cmd. Add a new driver for this
suite, cmdline.py. This driver reads arguments from the test,
and executes the server with these arguments. Server output
is passed on as test result.

@todo: It's not necessary to start/stop the server
for 'cmd' suite. Will be fixed when how to start/stop
server is defined in suite.ini (we'll then be
able to define a no-op start/stop routines).
@todo tarantool_silverbox output is hard to auto-verify
since it contains the current time and process id.
Either implement a way to mask out pieces of output
from the result file (preferrable), or change
tarantool to not output volatile data.

test-run.py modified: we now can preprocess suite.ini
"client" parameters, and substitute $constants in them,
e.g. $server.

@todo: provide ability to substitute $constants in .test
files as well.

Provide options to admin.py to use it not just as
a test console, but aslo as an interactive client.

* u64-indexes:
  [box] Add kostja's comments and simplify field_compare.
  [box] Correctly compare multicolumn indeces with NUM64 keys.
  [box] Remove experemental code.
  [box] Add support of u64 hash index.
  [box] Rename khash structures in more consistent way.
  [box] Add suport of u64 hash indeces.

Delete a temporary file used for build.

Fix 'make test' failure after pull from master.

Test runner: provide better comments, add a summary
of failing tests when running with --force.
Change indentation.
