b4e9f2392c Update elftoolchain to upstream rev 3130
This includes a number of libdwarf improvements (particularly DWARF4
related) and updates to elftoolchain tools such as strip(1). It also
includes a large number of miscellaneous fixes (memory leaks, sign and
cast warnings, integer overflow and underflow, etc.).

This is a merge of r276167,276170-276172 from the
projects/elftoolchain-update-r3130 branch.

9ef62fdb87 Set up default shstrtab entries at shstrtab initialization
Instead of waiting until the addition of the first non-default entry.
This fixes a segfault when strip(1) is asked to remove every section from
an object file.

a356a1f51f Do not strip all when stripping an explicit symbol
When requested to strip specific symbols (-N flag) the default should be
to strip nothing (other than the requested symbols). This is consistent
with binutils strip(1).

30568ad37e Correct elftoolchain strip(1) memory size calculation
Calculate the segment's memory size (p_memsz) using the virtual
addresses, not the file offsets. Otherwise padding preceeding SHT_NOBITS
sections may be excluded from the calculation, resulting in a segment
that is too small.

ccbdcd03f2 libelf: Fix cross-endian ELF note file / memory conversion
The namesz and descsz variables need to be used in native endianness.
The sizes are in native order after swapping in the file to memory case,
and before swapping in the memory to file case.

This issue was identified for r273443, but the change was applied to the
wrong case. Revert r273443 to fix the to-memory case, and apply the
equivalent change to the to-file case.

c10185837c Fix the conversion macro for .note sections, broken in the case
the ELF file's byte order is not the native byte order.  The
bug is that the variables holding the name and description size
are used (natively) after having been byte-swapped.  The fix is
to calculate sz from them just prior to byte-swapping.

5da7d44acb GCC for PowerPC does not align .note sections to 4 bytes. When
running ctfmerge on its objects, libelf asserts as it expects
.note sections to be 4-byte aligned.  Change that expectation.

9c016dc4b2 API dwarf_attrval_flag() should properly handle an attribute with
(DWARF4) form DW_FORM_flag_present which implicitly indicates the
presence of the attribute. Manual page is updated to reflect this
change.

Note that this was previously fixed in the old libdwarf.

4e5c697507 Use FreeBSD's ELF headers instead of the elfdefinitions.h header which
comes with elftoolchain. This version of libelf doesn't need to be
portable; using FreeBSD's own ELF headers will avoid conflicts and
make integration easier.
