Keep track of symbol reference count for each DSO. The ref count is
increased when a DSO symbol is added to the import table, and
decreased when a DSO symbol is removed from the import table. After
symbol resolution finished, ld will know which DSO is actually needed
by looking at the reference count.

Overhaul of section layout: Previously, each input section is matched
against all the wildcard list defined in the linker script for output
sections to determine where to insert it. This is incredibly
slow. This commit adds a hash table to record previous search results
in the wildcard list for a certain section name, so that if the same
section name is encountered again, linker can tell if there is a
wildcard list match by looking at the hash table.  After this change,
the wildcard list search time is reduced to negligible amount and
performance is increased dramatically.

Reverted previous change that the linker reads relocation at the same
time when loading symbols from input object. Loading relocation after
symbol resolution will actually save one pass of relocation traversal
later.  I feel that when linking bigger objects with larger number of
relocations, the time saved in relocation traversal will outweigh the
I/O time saved by loading relocation and symbols at the same time.

Set the sh_entsize of the output section based on the sh_entsize of
the input sections it contains. If all the input sections has the same
sh_entsize, the output section will also have that sh_entsize.  If any
input section has a different sh_entsize, the sh_entsize for output
section is set to 0, meaning that it has variable entry sizes.

should be set to the PLT address so function will have unified address

-----------
Improve compatibility with GNU ld: Do not complain about "no input
files" when option '-v', '-V' or '--verbose' is specified in the
command line and no input files are provided. Instead, the linker
should exit silently after printing version information.

Implement function "ld_reloc_gc_sections" that performs a breadth-first
search for sections referenced by relocations associated with "used"
sections, i.e, to find sections that should not be garbage-collected.
The initial set of "used" sections consists of sections containing
the entry symbol and extern (-u) symbols. The search is recursive:
"used" sections found are inserted to the set and their relocations
will be used to search for more "used" sections.
