Slightly reduces file size, improves build speed and makes build more
reproducible.
The .comment section contained GCC version information which could cause
different build output from just a minor update in GCC. The information is not
needed so we strip this.
The strip command was invoked using xargs, spawning a new process for each file.
This is inefficient as xargs can correctly run the strip command with multiple
file names.

Note that there is a slight distinction between
`not tx.is_complete()` and `isinstance(tx, PartialTransaction)`,
which is that technically you can have a PSBT that is already complete
but was not yet converted to a standard bitcoin tx.

Python 3.8 changed where DLLs are searched for.
see https://docs.python.org/3/whatsnew/3.8.html#bpo-36085-whatsnew
This potentially affect our binaries when we start shipping python 3.8+, however that is not being addressed here. This commit simply addresses the usecase of running from source, on Windows, using python 3.8.
On older Python, a user could build/obtain DLLs and place them anywhere on the system %PATH%, however this no longer works with py3.8, as %PATH% is no longer checked.
With py3.8, instead, we now check if there is a folder named '.dlls' in the top-level project directory, and if so, register that as an additional search path.
A user who wants to run Electrum from source on Windows using python 3.8 or later, with their custom DLLs, should manually create the '.dlls' folder and put their DLLs there. If they also want to switch between e.g. python 3.7 and 3.8, they should also include '.dlls' in the system %PATH%.
When using Electrum, interesting DLLs include at least libsecp256k1.dll, libusb-1.0.dll, libzbar-0.dll.
widget.show() and widget.setVisible(True) results in a blink of an ephemeral window containing the widget;
that is, unless the widget has a parent explicitly set or it can be determined via which layout the widget is placed in.

self.setMinimumHeight(h)
A variant of WaitingDialog that runs the task in the GUI thread,
blocking the GUI. It is probably a code smell to actually use this,
as operations should not block the GUI... still it provides a middle-ground
between blocking the GUI without giving user-feedback and having to refactor
existing code (to avoid blocking).
Note: the checksum was already being checked in practically all cases, by the caller.
Moved the check here, to the lower level (but still public) method for sanity.
For example, for 50 KB of random data, and base 43,
previously,
- base_encode took ~38 seconds
- base_decode took ~270 seconds
now,
- base_encode takes ~7.5 seconds
- base_decode takes ~6 seconds
