Adam Simpkins a3c582d708 check for std::generic_category when looking for errno errors 
Summary:
Add a new utils/SystemError.h header with helper functions to check if a
`std::system_error` contains an errno value.

Most of the code in Eden previously only checked for `std::system_category`
when looking for errno values.  `std::generic_category` is the correct category
to use for errno exceptions, but folly/Exception.h incorrectly throws them as
`std::system_category` today.  This change makes Eden treat either error type
as errno values for now.

Eden

Eden is a project with several components, the most prominent of which is a virtual filesystem built using FUSE.

Caveat Emptor

Eden is still in early stages of development. We are making it available now because we plan to start making references to it from our other open source projects, such as Buck, Watchman, and Nuclide.

The version that we provide on GitHub does not build yet.

This is because the code is exported verbatim from an internal repository at Facebook, and not all of the scaffolding from our internal repository can be easily extracted. The key areas where we need to shore things up are:

  • The reinterpretations of build macros in DEFS.
  • A process for including third-party dependencies (presumably via Git submodules) and wiring up the external_deps argument in the build macros to point to them.
  • Providing the toolchain needed to power the [undocumented] thrift_library() rule in Buck.

The goal is to get Eden building on both Linux and OS X, though Linux support is expected to come first.
