758f2bc556 eliminate the package global name space assumption in object files
5g/6g/8g: add import statements to export metadata, mapping package path to package name.
	recognize "" as the path of the package in export metadata.
	use "" as the path of the package in object symbol names.

5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package.

5l/6l/8l: rewrite "" in symbol names as object files are read.

gotest: handle new symbol names.

gopack: handle new import lines in export metadata.

Collectively, these changes eliminate the assumption of a global
name space in the object file formats.  Higher level pieces such as
reflect and the computation of type hashes still depend on the
assumption; we're not done yet.

a6736fa4ff cleanup toward eliminating package global name space
* switch to real dot (.) instead of center dot (·) everywhere in object files.
    before it was half and half depending on where in the name it appeared.
  * in 6c/6a/etc identifiers, · can still be used but turns into . immediately.
  * in export metadata, replace package identifiers with quoted strings
    (still package names, not paths).

3ca1b1d27f Continuation of issue 221 fix. When 8g or 6g or 5g are called with a
UTF-8 string, Yconv() converts it into an octal sequence. If the
string converted to more than 30 bytes, the str buffer would
overflow. For example, 4 Greek runes became 32 bytes, 3 Hiragana
runes became 36 bytes, and 2 Gothic runes became 32 bytes. In
8l, 6l and 5l the function is Sconv(). For some reason, only 5l uses
the constant STRINGSZ (defined as 200) for the buffer size.

6fc820729e go: makes it build for the case $GOROOT has whitespaces
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

Fixes #115.
