- API hook used for pseudo console support causes slow down. This patch limits API hook to only program which is linked with the corresponding APIs. Normal cygwin program is not linked with such APIs (such as WriteFile, etc...) directly, therefore, no slow down occurs. However, console access by cygwin.dll itself cannot switch the r/w pipe to pseudo console side. Therefore, the code to switch it forcely to pseudo console side is added to smallprint.cc and strace.cc.
v2: Unify set_ishybrid_and_switch_to_pcon() and CHK_CONSOLE_ACCESS() because they have exactly the same functionality.
