Retrieve the program header table for the given ELF descriptor elf. The number of elements in the
program header table can be retrieved with elf32_getphdrnum and elf64_getphdrnum. elf32_newphdr and
elf64_newphdr change the size of the program header table or to delete it. If changing an element of the
program header table, you must call elf_flagphdr with ELF_C_SET and ELF_F_DIRTY in order to write the new
data to disk.
