QWeb monetary widget uses the precision of the currency to know the number of
digits to display on a price. The number of digits is based on log10(rounding).
For currency with rounding different than 10^x (e.g. in Switzerland 0.05
to allow 5 cents coins only), the number of displayed digits should be rounded
up. e.g. log10(0.05) is -1.3, rounded up to 2 digits.

For instance, when a context was passed to a method, but no lang was defined in the context, it did not tried to fallback to other places where we could have find the user language.

Without this fix, if you have a new view in a module with active=False, the active tag will be ignore when upgrading the module because of 'update' mode, and the view will be activated by default !

[Fix] ir_translation: fix the problem of base_field object has no attribute model (Maintenance Case:618054)

Fixes #3859

This is safer to avoid inadvertently dropping customizations,
and does not impact the normal update/uninstall process, which
is based on the dependency order.

[FIX] fields: in *2many convert_to_write(), return all fields for new records and dirty fields for existing records

commit f76d4525 was not actually working: extra keys from
config files are not yet into the config options dict at
import time. The fix is to move the logic inside the method,
like in `find_pg_tool` just below.

Also fix the use of `find_in_path` in report.py: the subprocess
may also raise AttributeError exception, so instead of listing
all the possible ones just re-raise the IOError shallowed by
`find_in_path` when the result is None.

Fixes #3809 #3811

The openerp-server.conf now generates the bin_path record, in order
to resolve calls to external binaries served in the thirdparty dir.

Adpated report.py to use find_in_path and not directly which.

* use static imports in java examples to make them terser
* inline ``domain`` in java and php example to make examples more
  self-contained
* try to extend/improve Model.write's docstring
* add convenience kwarg to fields_get, mostly for user-driven
  introspection

Changing the decimal precision of float fields is a rare
operation, while cache clearing occurs fairly frequently.
Signaling a full registry change when the decimal precision
is changed (instead of a mere cache change) is therefore
a better trade-off, and more semantically correct as well.
This way we avoid the decimal precision refresh for each
invalidation.

Registry invalidation implies cache invalidation.

return False when calling is_running_as_nt_service from a non adminstrator
account.

Define a shim signal.SIGHUP on windows to avoid an ifdef in the threaded server
loop.

When a failure occurs, or when exiting an assertRaises(), the environment
should not contain fields to recompute.

When an onchange returns a change in a 2many field line (a '1' tuple, update), avoid to return all fields of the *2many field but only the altered field.

Otherwise, the web client regard all the fields of the 2many as dirty, and try to write on all fields (even if the value is the same, thus)

There was an issue in _setup_fields(): the method invokes _inherits_reload(),
which recomputes inherited fields, and invokes itself recursively on children
models.  This may be problematic if the children models have already been set
up.

This optimization avoids recursive calls of method _inherits_reload().  In
_setup_fields(), first all parent models are set up, then their fields are
inspected to determine inherited fields, and their setup is done.  This scheme
guarantees that inherited fields are computed once per model.

Note that serialized fields are ignored; they are no longer supported, anyway.

Whenever the longpolling/gevent worker dies, it
should be automatically restarted by the prefork
server, just like it happens for HTTP workers.
