803d8ff0d5 fix launcher creation for gracket[-text] on Mac OS 
The repair in 71a43f34c8 fixed the creation of some launchers, but it
broke GUI launchers with a relative reference on Mac OS.

47a2d4a879 Fixed tests for log function. 
The test cases relied on arity and changing log to have an arity
of both 1 and 2 activated new (incorrect) tests. I fixed the
incorrect tests as they applied to the log function.

922b5f06e9 Make log also accept a base. (#1667) 
Make `log` in `racket/base` optionally accept a second argument.

The second argument is the log `base`. The docs also recommend
`fllogb` when precision is important.

* Error message when base is 1
* Added docs.
* Add tests.

016b8009c5 repair "info-cache.rktd" assumption of relative paths 
Fix for 459a74455c to handle the case that a path
to record is not relative. The `raco pkg` tests
exposed the problem.

50f67cf6e4 remove @history for flat contracts #:exercise 
Remove the history annotation on `build-flat-contract` property
 about removing the `#:exercise` keyword.

Because the keyword wasn't actually removed from the function,
 only from the (incorrect) documentation. So there aren't any
 legal programs that depend on the removed keyword argument.

459a74455c avoid platform-specific path conventions in "info-cache.rktd" 
Store relative paths in "info-cache.rktd" (which corresponds,
roughly, to packages) in a platform-independent form, instead
of using the current platform's convention.

Using the current platform's covention works badly when
cross-compiling for Windows on Unix, since relative paths are used as
keys in the "info-cache.rktd" table. For example, updating a
pre-installed package on Windows mangles the mapping if the installer
is created from a cross-compiled installation.

to `(hash-ref <ht> <key> <constant>)` didn't check that the `lambda`
for had zero argument.

8da0be8031 fix relative references for license and acks in installer build 
The process of creating an installer involves building "racket-index"
in user scope, but the license and acks files are normally only in
installation scope. An explicit targeting of the installation-scope
output needs to be disabled when the documentats are rendered to
user scope.
