3dab0f2d1f Revert SHLIB_MAJOR to 2.
As discussed with kan@, since DTrace is the only consumer of libproc
right now, there's no need for a major shlib bump.

a049970caa New version of libproc. Changes are:
* breakpoint setup support
* register query
* symbol to address mapping and vice-versa
* more misc utility functions based on their Solaris counterpart

Also, I've written some test cases.

This is not yet enabled in the build because I also need to import a new

5df649f424 Redo fetch_read() using non-blocking sockets. This is necessary to
avoid a hang in the SSL case if the server sends a close notification
before we are done reading.  In the non-SSL case, it can provide a
minor (but probably not noticeable) performance improvement for small
transfers.

f2d14f41cf Build clang libraries by default with -fno-exceptions and with
-fno-rtti. The clang libaries that really use exceptions and virtual
functions can enable LLVM_REQUIRES_EH and LLVM_REQUIRES_RTTI
respectively. This saves space on the resulting binaries and follows
what's being done upstream.

49a7d97ce4 Perform additional checks when translating between file and memory
representations of ELF types.

The ELF(3) API allows applications to request a conversion that is
`in-place', i.e., with source and destinations data buffers being
the same.  However, the file and memory sizes of ELF sections that
have additional internal structure, such as those of type `Elf_Note',
or `Elf_GNU_Hash_Header', can be determined only known after the
type-specific headers that comprise the first few words in these
sections are read and translated.

Pass in the size of destination buffer to type translation routines
in "libelf_convert.m4" and have these routines return an error code
if the translated data would not fit inside the destination buffer.

19ba81c75a - Correctly handle sections of type SHT_NOBITS. For these sections:
- elf_getdata() and elf_rawdata() should return an "Elf_Data" structure
    that has its "d_buf" member set to NULL and "d_size" member set to
    the nominal 'size' of the section.  [1]
  - Update the manual page for these functions.
- Fix a memory leak in an error handling path inside elf_getdata().
- Use _libelf_allocate_data() in elf_newdata() for consistency.

b9a7e30aff Upgrade our Clang in base to r108428.
This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
has been renamed to /usr/include/clang/2.8.
