Mojo's libc support

Getting Started

The only dependency for libc is Mojo.

You can install Mojo following the instructions from the Modular website.

Once you have created a Mojo project using the magic tool,

Add the mojo-community channel to your mojoproject.toml, e.g:

[project]
channels = ["conda-forge", "https://conda.modular.com/max", "https://repo.prefix.dev/mojo-community"]

Add libc as a dependency:
```
[dependencies]
libc = ">=0.1.4"
```
Run magic install at the root of your project, where mojoproject.toml is located
libc should now be installed as a dependency. You can import libc functions from the library, e.g:
```
from libc import socket
```

See the examples in examples/sockets/ directory.

See the examples in examples/files/ directory.

To build the project, execute the following command:

./scripts/build.sh

To run the tests, execute the following command:

./scripts/run-tests.sh
