Michael K. Werle ed5fcbb773 Add explicit message when noexec prevents library loading. 
Motivation:

Docker's `--tmpfs` flag mounts the temp volume with `noexec` by default,
resulting in an UnsatisfiedLinkError.  While this is good security
practice, it is a surprising failure from a seemingly innocuous flag.

Modifications:

Add a best-effort attempt in `NativeLibraryLoader` to detect when temp
files beng loaded cannot be executed even when execution permissions
are set, often because the `noexec` flag is set on the volume.

Requires numerous additional exclusions to the Animal Sniffer config
for Java7 POSIX permissions manipulation.

Result:

Fixes [#6678].

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
