37b40dab51 database/sql: stop reuse of bad connections
The second parameter for sql.putConn() (err) is always nil. As a result bad
connections are reused, even if the driver returns an driver.ErrBadConn.
Unsing a pointer to err instead achievs the desired behavior.
See http://code.google.com/p/go/issues/detail?id=3777 for more details.
Fixes #3777.

2281c3294b cmd/go: fix cgo linking on netbsd
NetBSD's built-in linker script for 'ld -r' does not provide a
SEARCH_DIR. As a result libgcc.a is not found when -lgcc is used.

Work around this by determining the path to libgcc (by invoking
gcc with the -print-libgcc-file-name option) and explicitly
referencing the resulting library.

   Fixes #3261.
   Fixes #1741.
   Added a testcase for linking in libgcc.

TODO:
1. still need to fix the INDIRECT_SYMBOL_LOCAL problem on Darwin/386.
2. still need to enable the libgcc test on Linux/ARM, because 5l can't deal
with thumb libgcc.

Tested on Darwin/amd64, Darwin/386, FreeBSD/amd64, FreeBSD/386, Linux/amd64,
Linux/386, Linux/ARM, Windows/amd64, Windows/386

d624f0c922 exp/html: simplify testing code
Now that the parser passes all tests in the test suite,
it is no longer necessary to keep track of which tests
pass and which don't. So remove the testlogs directory
and the code that uses it.
