Instead of adding SQLITE_API macros sqlite3.h while creating sqlite3.c, add them as part of generating the sqlite3.h target, while copying from sqlite.h.in to sqlite3.h. This fixes a build problem that was causing multiple SQLITE_API macros to be added to a single line of sqlite3.h, and the problem cited by #4016.

Changes to src/pager.c.

    14     14   ** The pager is used to access a database disk file.  It implements
    15     15   ** atomic commit and rollback through the use of a journal file that
    16     16   ** is separate from the database file.  The pager also implements file
    17     17   ** locking to prevent two processes from writing the same database
    18     18   ** file simultaneously, or one process from reading the database while
    19     19   ** another is writing.
