* Handle edge case in text drawer line length logic
There is an edge case in the initial line length logic for the text
drawer. When it's trying to figure out how long a line should be it
initially tries various methods to determine the length. But, it only
checks for a None response from those initial checks. It's possible a 0
could be returned. Later we check if the value of the line_length is
true, which it won't be for a 0 value. In that case we unconditionally
use the class variable line_length which if not initialized is None. In
this case we'll hit an error further down trying to compare None to an
int. This commit fixes this by checking the value of self.line_length
before using it and defaulting to the value of get_terminal_size() if
it's not true.
* Simplify line length logic
* Use pylatexenc utf8tolatex for gate names in latex drawer
When the latex drawer goes to draw custom gates they can be named and
valid unicode string. That's because the gate name attribute is a
string. However, latex doesn't know how to handle all utf8 characters
and requires escaping or custom libraries to render many of them.
Instead of trying to handle every edge case this commit uses the
pylatexenc lib (which is a MIT licensed lib with no additional
dependencies) which contains a mapping of all the unicode characters
with the latex equivalent. This means that things like '_' in custom
gate names will render properly now.
Partially Addresses #2235
* Fix lint
* Add example for stochastic swap and use to verify wheels
This commit adds a new example to the examples directory for running the
stochastic swap pass. This is then used by the wheel build automation
to verify the built wheel works as expected. The compiled code (and
complexity in the wheel build) is for the stochastic swap pass so
verifying it functions when installed from the built wheel is important.
* Test wheel build with new script
Comment out branch logic and wheel upload to verify the wheel build this
is just for testing and will be reverted before the PR merges.
* Remove prints from example
* Revert "Test wheel build with new script"
This reverts commit f5edc1c777.

* Remove f-strings for python 3.5 compatibility. Change cnot_decompose() to two_qubit_cnot_decompose()
* Handle opaque instructions and identity in qobj_to_circuits
This commit fixes the qobj_to_circuits converter to handle opaque/custom
instructions that aren't decomposed in the qobj. At the same time the
identity gate handling is fixed because it is a special case where the
gate name doesn't match the function name (id vs iden()) and needs to be
handled that way.
* Add test
* Fix lint
* Fix lint and test imports
* Just use getattr for params
* Override getattr for qiskit._util
The backwards compat shim qiskit._util previously emitted a deprecation
in the raw module. This was done for simplicity and so that it would
only be emitted during import. However, since it's in the base namespace
it would be imported every time qiskit was imported, which led to a
deprecation warning always being emitted. To work around this issue,
this commit defines a custom __getattr__ for the module which will emit
the deprecation warning and call qiskit.util. This should limit the
deprecation warnings to just when qiskit._util is accessed.
Fixes#2252
* Remove warning from qiskit._util and rely on a comment
Since the warning was too noisy and gets emitted on every qiskit import
this commit just removes it. The _util module is still deprecated, and
listed as such in the module and in the changelog (and the future
release notes). But, since it was marked as private previously weighing
the noise of advertising the deprecation with a warning against the
potential of an external user using it removing the warning seems the
better option.
* Add changelog
As part of some peoples desire to remove underscores from module names
the qiskit._util module was renamed to qiskit.util. However external
utilities, namely Aer, were using the public function in this module. To
ensure a smooth transition when we release 0.8 this commit adds a compat
shim qiskit._util module that just provides everything from qiskit.util.
But it raises a deprecation warning when imported that it has been
renamed and qiskit._util will be removed for 0.9.

* Add user config file for local settings
This commit adds the concept of a user config file to set local defaults
when using qiskit-terra. This enables the end user to override the
default values for some commonly used terra functions in their local
environment. Right now this only includes the backend used by the
circuit drawer, but it will be expanded in the future as more settings
with opinionated defaults are exposed. To set a config file you can
either create one in the default location
'~/.config/qiskit/settings.conf' or use the QISKIT_SETTINGS environment
variable to specify an alternative location.

* Skip tempfile tests on windows
Since I can't figure out a reliable way to mock open on python 3.5 and
3.6 (it works fine on 3.7) this commit just skips the tests that used to
use tempfile and sets them to skip on windows environments, since they
don't work on appveyor.
* Remove unused import
These tests haven't run in a long time, they skip (not silently but
among all the test results no one notices) They also don't work
currently even if we fix the original breakage. If we're not
cross-testing terra master on aer and vice versa keep these tests in
terra don't provide value (although travis and appveyor limit how much
we can do there). We can revisit adding them back in the future if
needed.
