Commit Message

Add search for libc binary by leaked function addresses (#2103)

* libcdb: Add option to search by function offsets

When you're able to leak addresses of the libc library, use `libcdb.search_by_symbol_offsets()` to find and download the matching libc library from https://libc.rip.

If there are multiple matches, the user is prompted to select one interactively. The selection can be saved in the code for future executions of the script.

Fixes #1867

* libcdb: Handle multiple results when looking up by hash

Sometimes the same library appears to be indexed multiple times (see 0b52d2e71). Handle that situation by selecting the first in the list, since they should all be identical given the same hash value.

* Update CHANGELOG

* Fix off-by-one when pre-selecting a libc

* Do .json() only once

Module-level documentation would go here, along with a general description
of the functionality.  You can also add module-level doctests.

You can see what the documentation for this module will look like here:
https://docs.pwntools.com/en/stable/testexample.html

The tests for this module are run when the documentation is automatically-generated
by Sphinx.  This particular module is invoked by an "automodule" directive, which
imports everything in the module, or everything listed in ``__all__`` in the module.

The doctests are automatically picked up by the ``>>>`` symbol, like from
the Python prompt.  For more on doctests, see the `Python documentation
<https://docs.python.org/2/library/doctest.html>`_.

All of the syntax in this file is ReStructuredText.  You can find a
`nice cheat sheet here <https://github.com/ralsina/rst-cheatsheet/blob/master/rst-cheatsheet.rst>`_.

Here's an example of a module-level doctest:

    >>> add(3, add(2, add(1, 0)))
    6

If doctests are wrong / broken, you can disable them temporarily.

    >>> add(2, 2) # doctest: +SKIP
    5

Some things in Python are non-deterministic, like ``dict`` or ``set``
ordering.  There are a lot of ways to work around this, but the
accepted way of doing this is to test for equality.

    >>> a = {a:a+1 for a in range(3)}
    >>> a == {0:1, 1:2, 2:3}
    True

In order to use other modules, they need to be imported from the RST
which documents the module.

    >>> os.path.basename('foo/bar')
    'bar'

def add(a, b):
    '''add(a, b) -> int

    Adds the numbers ``a`` and ``b``.

    Arguments:
        a(int): First number to add
        b(int): Second number to add

    Returns:
        The sum of ``a`` and ``b``.

    Examples:
