Genode application binary interface (ABI) This patch decouples the kernel-specific implementation of the dynamic linker from its kernel-agnostic binary interface. The name of the kernel-specific dynamic linker binary now corresponds to the kernel, e.g., 'ld-linux.lib.so' or 'ld-nova.lib.so'. Applications are no longer linked directly against a concrete instance of the dynamic linker but against a shallow stub called 'ld.lib.so'. This stub contains nothing but the symbols provided by the dynamic linker. It thereby represents the Genode ABI. At system-integration time, the kernel-specific run/boot_dir back ends integrate the matching the kernel-specific variant of the dynamic linker as 'ld.lib.so' into the boot image. The ABI symbol file for the dynamic linker is located at 'base/lib/symbols/ld'. It contains the joint ABI of all supported architectures. The new utility 'tool/abi_symbols' eases the creation of such an ABI symbol file for a given shared library. Its result should be manually inspected and edited as needed. The patch removes the 'syscall' library from 'base_libs.mk' to avoid polluting the kernel-agnostic ABI with kernel-specific interfaces.

Clean up base-library structure This patch moves the base library from src/base to src/lib/base, flattens the library-internal directory structure, and moves the common parts of the library-description files to base/lib/mk/base.inc and base/lib/mk/base-common.inc. Furthermore, the patch fixes a few cosmetic issues (whitespace and comments only) that I encountered while browsing the result.
