use set_pin_mode() to set uart pinmux (#158) 
Use set_pin_mode() to set pinmux for UART
RX and TX pins. This is similar effect as
running the config-pin utility.

Fix seg fault of PWM in Python 3.6 (#189) 
PWM.set_frequency() and PWM.set_duty_cycle()
were resulting in a seg fault inside the
call to PyArg_ParseTupleAndKeywords().

close enable_fd when stopping PWM output (#197) 
Issue #197: JesseMcL raised the issue that running
PWM.start() and PWM.start() in a loop will eventually
exhaust the number of open file descriptors and
PWM.start() will raise the error:

  RuntimeError: problem with sysfs file.

The file descriptor for the enable file should
be closed in pwm_disable() to avoid the leak

b65cbf8e41 sleep to avoid udev race condition #185 
sleep 100 ms after export to avoid race condition as udev
needs the opportunity to set group ownership and permission

Test instructions:
==================
reboot, log back in, wait for udev to set group ownership and permission:

$ ls -la /sys/devices/platform/ocp/48304000.epwmss/48304200.pwm/pwm/pwmchip6/export
-rw-rw---- 1 root pwm 4096 Nov  2 04:02 /sys/devices/platform/ocp/48304000.epwmss/48304200.pwm/pwm/pwmchip6/export

run test program:

python ~/issue185.py

contents of test program:

import Adafruit_BBIO.PWM as PWM
PWM.start("P8_13", 50, 1000, 0)
PWM.stop("P8_13")
PWM.cleanup()

58eb54679c Attempt to use udev ecap path for pwm path 
Example of pwm and ecap paths for pwm outputs in the 4.14 kernel:

/sys/devices/platform/ocp/48300000.epwmss/48300100.ecap/pwm/pwmchip0/pwm-0:0/duty_cycle
/sys/devices/platform/ocp/48300000.epwmss/48300200.pwm/pwm/pwmchip1/pwm-1:0/duty_cycle
/sys/devices/platform/ocp/48300000.epwmss/48300200.pwm/pwm/pwmchip1/pwm-1:1/duty_cycle
/sys/devices/platform/ocp/48302000.epwmss/48302200.pwm/pwm/pwmchip3/pwm-3:0/duty_cycle
/sys/devices/platform/ocp/48302000.epwmss/48302200.pwm/pwm/pwmchip3/pwm-3:1/duty_cycle
/sys/devices/platform/ocp/48304000.epwmss/48304100.ecap/pwm/pwmchip5/pwm-5:0/duty_cycle

Note that the ecap path is longer than pwm path by 1 character
