* disallow embedding of C type (Fixes issue 2552)
* detect 0-length array (Fixes issue 2806)
* use typedefs when possible, to avoid attribute((unavailable)) (Fixes issue 2888)
* print Go types constructed from C types using original C types (Fixes issue 2612)
This fix changes _cgo_export.h to repeat the preamble from import "C".
Otherwise the fix to issue 2612 is impossible, since it cannot refer to
types that have not been defined. If people are using //export and
putting non-header information in the preamble, they will need to
refactor their code.

Makes files like src/pkg/syscall/ztypes_linux_amd64.go easier to read.
(The copy that is checked in predates the //line output mode,
so this also preserves the status quo.)

If a printer is configured with the SourcePos mode
set, it will emit //-line comments as necessary to
ensure that the result - if reparsed - reflects the
original source position information.
This change required a bit of reworking of the
output section in printer.go. Specifically:
- Introduced new Config mode 'SourcePos'.
- Introduced new position 'out' which tracks the
position of the generated output if it were read
in again. If there is a discrepancy between out
and the current AST/source position, a //line
comment is emitted to correct for it.
- Lazy emission of indentation so that //line
comments can be placed correctly. As a result,
the trimmer will have to do less work.
- Merged writeItem into writeString.
- Merged writeByteN into writeByte.
- Use a []byte instead of a byte.Buffer both in the
printer and in the trimmer (eliminates dependency).
Also: introduced explicit printer.Mode type (in
sync w/ parser.Mode, scanner.Mode, etc.)
Runs all tests. Applied gofmt to src, misc w/o changes.

Consequently, remove many package Makefiles,
and shorten the few that remain.
gomake becomes 'go tool make'.
Turn off test phases of run.bash that do not work,
flagged with $BROKEN. Future CLs will restore these,
but this seemed like a big enough CL already.

Only ParseFile, ParseDir, and ParseExpr are used in the tree.
If partial parsing of code is required, it is fairly simple
to wrap the relevant piece of code into a dummy package for
parsing (see parser.ParseExpr).
Also: minor cleanups.

- Changed the Scan API semantics slightly:
The token literal string is only returned
if the token is a literal, comment, semicolon,
or illegal character. In all other cases, the
token literal value is determined by the token
value.
Clients that care about the token literal value
when not present can always use the following
piece of code:
pos, tok, lit := scanner.Scan()
if lit == "" {
lit = tok.String()
}
- Changed token.Lookup API to use a string instead
of a []byte argument.
- Both these changes were long-standing TODOs.
- Added BenchmarkScan.
This change permits a faster implementation of Scan
with much fewer string creations:
benchmark old ns/op new ns/op delta
scanner.BenchmarkScan 74404 61457 -17.40%

Also rename -v to -x in the build and install commands,
to match the flag in go test (which we can't change
because -v is taken). Matches sh -x anyway.

In some rare cases, gofmt would accept more than the maximum
number of empty lines (1) between source code snippets.
The actual change is in printer.go, lines 773-775; the rest
is some minor restructuring.

clean is gone; all the intermediate files are created
in a temporary tree that is wiped when the command ends.
Not using go/build's Script because it is not well aligned
with this API. The various builder methods are copied from
go/build and adapted. Probably once we delete goinstall
we can delete the Script API too.

This is the result of running `gofix -r hashsum` over the tree, changing
the hash function implementations by hand and then fixing a couple of
instances where gofix didn't catch something.
The changed implementations are as simple as possible while still
working: I'm not trying to optimise in this CL.

- syscall (not os) now defines the Errno type.
- the low-level assembly functions Syscall, Syscall6, and so on
return Errno, not uintptr
- syscall wrappers all return error, not uintptr.

Godefs was a C program that ran gcc and then parsed the
stabs debugging information in the resulting object file to
generate C or Go code for bootstrapping as part of
package runtime or package syscall.
Cgo does the same work, but using the dwarf debugging
information. Add -godefs and -cdefs options to cgo that
mimic godefs's output, albeit with different input
(a Go program, not a C program).
This has been a "nice to have" for a while but was forced
by Apple removing stabs debugging output from their
latest compilers.
Fixes#835.
Fixes#2338.

When the C API being used includes multiple names for the same
underlying symbol (e.g. multiple #define's for the same variable), then
cgo will generate the same placeholder variables for each name. This
then prevents the code from compiling due to multiple declarations of
the same variable - so change cgo to only create one instance of the
variable for the underlying symbol.
