The debug/dwarf package cannot parse the format generated here,
but the format can be changed so it does.
After this edit, tweaking the expression defining the offset
of a struct field, the dwarf package can parse the tables (again?).

Added a complement to (*File).Symbols for the dynamic symbol table.
Would be useful, for instance, if seraching for certain shared objects
compatible with certain libraries (for instance, LADSPA requires an
exported symbol "ladspa_descriptor").
Added a variable ErrNoSymbols that canonicalizes a return from
(*File).Symbols and (*File).DyanmicSymbols if the file has no symbols.
Added tests for both (*File).Symbols and (*File).DynamicSymbols;
there was never a test for (*File).Symbols at all. A small C program using
libelf, included in the test data, was used to produce the golden
symbols to compare against.
As part of the requirements for testing, (*File).Symbols and (*File).DynamicSymbols now document the order in which the symbol tables are returned (in the order the symbols appear in the file).
All tests currently pass.

Found using the vet check in CL 106370045.
This is a second attempt at CL 101670044, which omitted the deps_test change.
This adds dependencies to net/rpc:
encoding
encoding/base64
encoding/json
html
unicode/utf16
The obvious correctness and security warrants the additional dependencies.

When we've switched to 8K pages,
heap started to grow by 128K instead of 64K,
because it was implicitly assuming that pages are 4K.
Fix that and make the code more robust.

size instead of abusing text symbol
cmd/addr2line needs to know the virtual address of the start
of the text segment (load address plus header size). For
this, it used the text symbol added by the linker. This is
wrong on amd64. Header size is 40 bytes, not 32 like on 386
and arm. Function alignment is 16 bytes causing text to be
at 0x200030.
debug/plan9obj now exports both the load address and the
header size; cmd/addr2line uses this new information and
doesn't rely on text anymore.

NetlinkRIB is currently allocating a page sized slice of bytes in a
for loop and it's also calling Getpagesize() in the same for loop.
This CL changes NetlinkRIB to preallocate the page sized slice of
bytes before reaching the for loop. This reduces memory allocations
and lowers the number of calls to Getpagesize() to 1 per NetlinkRIB
call.
This CL reduces the allocated memory from 141.5 MB down to 52 MB in
a test.

Fixes#8165.
After this change, the panic is replaced by a message:
$ go build -o out ...doesntexist
warning: "...doesntexist" matched no packages
no packages to build
The motivation to return 1 exit error code is to allow -o flag
to be used to guarantee that the output binary is written to
when exit status is 0. If someone uses an import path pattern
to specify a single package and suddenly that matches no packages,
it's better to return exit code 1 instead of silently doing nothing.
This is consistent with the case when -o flag is given and multiple
packages are matched.
It's also somewhat consistent with the current behavior with the
panic, except that gave return code 2. But it's similar in
that it's also non-zero (indicating failure).
I've changed the language to be similar to output of go test
when an import path pattern matches no packages (it also has a return status of
1):
$ go test ...doesntexist
warning: "...doesntexist" matched no packages
no packages to test
