Lonami Exo b6b4ea669d Remove messy subclassing in the TelegramClient
Since it was easy to cause MRO inconsistencies, and it's
not really needed now that self is type hinted as the client.

class ButtonMethods:
@staticmethod
def build_reply_markup(

"""
Builds a :tl:`ReplyInlineMarkup` or :tl:`ReplyKeyboardMarkup` for
the given buttons.
Does nothing if either no buttons are provided or the provided
argument is already a reply markup.
You should consider using this method if you are going to reuse
the markup very often. Otherwise, it is not necessary.
This method is **not** asynchronous (don't use ``await`` on it).
Arguments
buttons (`hints.MarkupLike`):
The button, list of buttons, array of buttons or markup
to convert into a markup.
inline_only (`bool`, optional):
Whether the buttons **must** be inline buttons only or not.
Example
.. code-block:: python
from telethon import Button
markup = client.build_reply_markup(Button.inline('hi'))
client.send_message('click me', buttons=markup)
