dea19c7374 fuchsia: Port ElfImageReader and (some of) its tests 
(Still need to avoid fork()-dependence for the non-self tests.)

8bbe985004 elf: Use d_ptr instead of d_val when reading from a dynamic array 
The dynamic array reader should treat data as unsigned when initially
reading values from the array to prevent premature sign-extension. The
glibc and traditional android headers define d_val using Elf32_Word, an
unsigned type. linux/elf.h, used by unified android headers, defines
d_val using Elf32_Sword, a signed type. Use d_ptr instead since it's
always an unsigned type.

Only a Linux implementation for now, but similar code for other
OSes can move behind it in the future.
